There are more of Klopp's fingerprints over the 2016-17 squad, and the thrashing of Barcelona — Lionel Messi and Luis Suarez both started in that game — is perhaps a sign that the methods of the charismatic, bespectacled German are starting to make a difference.

"We didn't think before the game we were on a level with Barcelona and we don't think now we are on a higher level than them," Klopp said. "We are not crazy. But you win 4-0 and you have to use it." Liverpool, a five-time European champion, always loves its European nights but the team's failure to qualify for continental competition this season may well turn out to be a blessing.

Klopp's men struggled with the packed schedule last season, resulting in vastly differing performances one week to the next. Players found it hard to enact Klopp's favored high-energy pressing style three games a week, and should be more consistent this season with a less-cluttered fixture list.

Especially domestically, there were obvious areas where Liverpool needed to make improvements. One was in defense, and Klopp has changed things round at center back by agreeing to the departure of Martin Skrtel and Kolo Toure, and bringing in Joel Matip from Schalke and Estonia captain Ragnar Klavan.

Left back was also a problem position, and Klopp tried out James Milner — a versatile midfielder — in that position against Barcelona before he got injured. Alberto Moreno is the first-choice left back but is error-prone, and Jon Flanagan has been loaned to Burnley for the season.

Klopp also struggled to settle on a regular starting center forward, with Daniel Sturridge and Danny Ings beset by injuries, Divock Origi adjusting to life in England in his first season in the Premier League and Christian Benteke failing to justify his $50 million price tag.

No new strikers have been signed, though. Klopp has said Benteke would be allowed to leave on a permanent transfer and Brazil forward Roberto Firmino is another option in the central-striker role, with Liverpool flush with attacking midfielders.

Midfield looks to be Liverpool's strongest asset like it was last season, when Philippe Coutinho, Firmino and Adam Lallana often produced moments of class. Two more exciting midfielders have been added, with Sadio Mane and Giorginio Wijnaldum joining for more than 50 million pounds ($65 million) combined.

Following the sale of Jordon Ibe to Bournemouth, Sheyi Ojo could get more game time and the 19-year-old looks to be the latest in a string of talented wingers to come through Liverpool. Ojo has been compared to Raheem Sterling, who left Liverpool for Manchester City last year.

With Liverpool completing work on renovating the main stand at Anfield, the team's opening three games will be away from home, starting at Arsenal on Sunday.

Efimova is being allowed to compete at the Rio de Janeiro Games following a 16-month suspension for doping and despite another positive test this year for the now-banned substance meldonium. The 24-year-old Russian is a flashpoint in her country's doping scandal because of her two infractions.

When Efimova waved a No. 1 finger after her semifinal on Sunday, King leaned back and gave her own version toward Efimova's face on a TV monitor. King then qualified fastest for the eight-woman final in 1 minute, 5.70 seconds, just ahead of Efimova's time of 1:05.72.

The two women square off in the 100-meter breaststroke final Monday night, swimming next to each other. Efimova's positive test for meldonium was placed on hold while world anti-doping officials conduct further studies on the drug.

"If that's what she feels she needs to be able to compete, whatever, that's her deal," King told reporters. "I'm here to compete clean for the U.S. and that's what I'm going to do." A smattering of boos greeted Efimova after she won her preliminary heat Sunday. The Russian men's 4x100 freestyle relay was also booed when introduced for their final the same night.

Ruta Meilutyte of Lithuania, the world record holder in the 100 breast, said Efimova's doping history is disrespectful to other athletes. "We train fair," she said. "When something like that happens, it's never nice. These are not the values of our sport."

Kirsty Coventry of Zimbabwe, a seven-time Olympic swimming medalist competing in Rio, serves on the International Olympic Committee's athletes' commission. "Hopefully, that ban made her clean in a way," she said of Efimova. "Hopefully, people that are cheating now know that they're going to get caught. It's just a matter of time. It's a little disappointing that there are certain people that are here."

As part of the International Olympic Committee's decision not to throw the entire Russian team out of the Olympics, Efimova was initially banned along with six other Russian swimmers who either had positive tests on their record or were named in an investigation of Russia's massive, state-sanctioned doping scheme.

Now, it looks like they'll all be competing in Rio de Janeiro, though world swimming body FINA has not fully explained why. Efimova is also expected to swim the 200 breaststroke and presumably the 4x100 medley relay.

Efimova declined to speak with reporters after the semifinals, but promised to talk after Monday's final. Earlier Sunday, she described the last six months as "crazy" and said she didn't "understand what's going on."

When pressed about criticism from rival swimmers and coaches, she smiled and walked away. U.S. swimmer Dana Vollmer said King and Katie Meili assumed all along that Efimova would be racing in Rio and prepared accordingly. Meili also advanced to the final.

"She has something to prove," Vollmer said of King. "That question (about Efimova) kind of adds some fire to a lot of us. Lilly is doing an amazing job of directly putting that into her racing." Winning gold and in the process beating Efimova would be especially meaningful to King, who will be a sophomore at Indiana University this fall.

"Obviously it would be great with all the doping things going on in the past year or two," she said. "It would be a really great moment for the U.S." Coventry struggles with the knowledge that sometimes cheating athletes do get a precious moment on the world stage, receiving Olympic medals in the limelight only to get caught later. Then their medal is taken away and re-awarded to another athlete when the world is no longer watching.

"That is hard," she said. "That will be heartbreaking for a lot of athletes."

Ibrahimovic headed in an 83rd-minute winner on Sunday as United beat Leicester 2-1 in the Community Shield — the traditional curtain-raiser to the English season — and give Mourinho his first piece of silverware as Old Trafford.

"That's what it's all about, winning trophies," Ibrahimovic said. "This is why I came. Hopefully I can win much more than this." On the day United moved closer to signing Paul Pogba in potentially a world-record transfer, its most high-profile offseason signing so far made an immediate impact, despite having a quiet game by his high standards at Wembley Stadium.

Ibrahimovic was lurking at the back post when Antonio Valencia floated over a cross from the right wing. Beating Wes Morgan in the air, Ibrahimovic planted a downward header against the post and the ball rebounded over the line.

The Community Shield is nothing more than a friendly match between the winners of last season's Premier League (Leicester) and FA Cup (United), but both teams treated it seriously and Ibrahimovic proudly hailed it as the 31st title of his trophy-filled career.

"Something big is going on with our team," Ibrahimovic said, before walking with his teammates up the Wembley steps to lift the shield to explosions of ticker-tape. Eleven weeks after scoring an extra-time winner for United in the FA Cup final at Wembley, Jesse Lingard returned to the stadium to put his team ahead in the 32nd minute with a solo goal that started 45 meters out. He slalomed past both of Leicester's center backs, Robert Huth and Morgan, darted past Danny Simpson and slid a finish under goalkeeper Kasper Schmeichel.

Jamie Vardy equalized for the league champions in the 52nd, pouncing on a short back pass from Marouane Fellaini, who had done well initially to track back and break up play. However, his pass to goalkeeper David de Gea was underhit, allowing the alert Vardy to round De Gea and shoot in left-footed from an acute angle.

Mourinho blamed Fellaini's mistake on the slowness of the Wembley field. Ahmed Musa, Leicester's club-record signing this offseason, was brought on at halftime and his pace, allied to Vardy's, worried United. Eric Bailly, one of United's three signings so far, lost his composure after a strong first half and was booked for fouls on Musa and Vardy.

Musa missed a great chance — a header from five meters out — before Ibrahimovic's goal. In injury time, Mourinho took off Juan Mata, who had only been on the field 30 minutes as a substitute. Mata, who was sold to United by Mourinho when the coach was at Chelsea, looked unhappy at a decision that was Mourinho at his ruthless best.

Victory was all that mattered to the Portuguese coach, who hopes to soon be welcoming Pogba to Old Trafford after United announced earlier Sunday that the Juventus midfielder was set for a medical examination.

"It's an important victory but we have lots of work to do," Mourinho said. "It was a positive performance for this moment of the season. It's always important to start with a trophy."

After her victory was announced, Kelmendi hugged Giuffrida and then walked off the mat in tears. Wearing a blue uniform — one that matched some of the Kosovo flags being waved in the arena — a teary Kelmendi waved to the crowd and raised her arms.

Kelmendi has struggled for years to represent her country, which declared independence from Serbia in 2008, in the Japanese martial art. At the 2012 London Games, she represented Albania because Kosovo was not recognized by the International Olympic Committee until 2014. Four years ago, Kelmendi lost to Christianne Legentil of Mauritius in the second round. In Rio de Janeiro, the two met again and Kelmendi advanced.

The 24-year-old Kelmendi is also a former world champion and was her country's flagbearer when the eight-member Kosovo team walked in the opening ceremony. She has Kosovo and Albanian citizenship and started judo in Sarajevo when she was 8, when her sister convinced her to give it a try.

To get to the final, Kelmendi defeated Misato Nakamura, a three-time world champion from Japan who won a bronze medal at the 2008 Beijing Games and repeated the feat in Rio. The other women's bronze medal went to Natalia Kuziutina of Russia.

In the men's 66-kilogram division, Fabio Basile of Italy surprised top-ranked An Baul of South Korea by flipping him for an immediate victory less than two minutes into the fight. Baul had been dominant in his earlier matches.

The bronze medals were won by Rishod Sobirov of Uzbekistan and Masashi Ebinuma of Japan.
