World Cup: Which teams are playing today?

Japan made five changes from their team that beat Germany in their World Cup opener as they face Costa Rica on Sunday.

Attackers Ritsu Doan, who came on and scored against Germany, Yuki Soma, and Ayase Ueda come into the starting line-up as Japan looks to take a big step towards the knockout round.

Right-back Miki Yamane replaces the injured Hiroki Sakai, while fit-again midfielder Hidemasa Morita comes in for Ao Tanaka.

Costa Rica make only two changes to the team that started the campaign with a 7-0 drubbing at the hands of Spain in Group E.

Teenage winger Jewison Bennette and defender Carlos Martinez drop to the bench, with Gerson Torres and Kendall Waston replacing them.

Japan sashayed through Germany's defense to win their opening World Cup game but captain Maya Yoshida said the Blue Samurai cannot afford to "dance badly" against Costa Rica on Sunday. Japan stunned the Germans 2-1 and now has the chance to take a big step towards the knock-out stage when they face a wounded Costa Rica in Group E.

The Central Americans opened their campaign on the wrong end of a 7-0 hiding by Spain but Yoshida insists Japan will not take their opponents lightly. "The spotlight is on us after the last game and we have to make sure that we don't dance badly," the defender said on Saturday. "Make no mistake, when you win it makes you feel more comfortable. We have to stay calm, prepare well and concentrate on the plan to get us the win. "We're not through yet." Yoshida said that the Japanese media have tended to focus on the team's games against European heavyweights Germany and Spain ever since the draw was made, with the Costa Rica clash being "pushed to one side". The captain is wary of a Costa Rican backlash after their Spanish humiliation. "They got hammered in their previous game so I think they're really going to go for it," he said.

Belgium coach Roberto Martinez will be looking for a vastly improved performance from his side when they take on a resolute Morocco in their second World Cup Group F fixture at Al Thumama Stadium on Sunday, where victory will seal a round of 16 places.

Martinez described their 1-0 win over Canada on Wednesday as the "worst technical performance" of his six-year spell in charge but said his team will improve as the tournament goes on.

"We have to grow with these games," he told reporters. "This tournament is going to make you develop and grow as it goes on. If you do that by winning games, it's an incredible advantage. "We didn't win (against Canada) with our normal talent and quality on the ball, but you don't win in the World Cup if you don't do the other side of the game (defend well)."

Morocco also has a concern over one of their key names after Noussair Mazraoui was stretchered off in the 0-0 draw with Croatia. It is not clear whether the right-sided player will recover from the hip injury in time. It was a workmanlike performance against the Croats but one that new coach Walid Regragui feels gives them a platform to build on against Belgium. "I've only been here for two months and I'm proud of the players. We wanted to achieve another result, but in the end, we were satisfied with the draw," he said.

Canada manager John Herdman said on Saturday his team was fired up for a test against 2018 World Cup finalists Croatia after the Canadians fell to Belgium 1-0 despite outplaying them. Canada, taking part in their second World Cup, is still looking to score their first goal in the history of the men's tournament. They qualified for the tournament in 1986, where they crashed out at the group stage both winless and goalless. Canada faces Croatia, who drew Morocco 0-0 in their opener, on Sunday in what Herdman described as a "massive game" "It's a hell of a test for this team. We are excited," Herdman told a news conference.

Germany faces a fight for World Cup survival on Sunday in a must-win clash with Spain as Japan and Belgium look to seal their place in the last 16. For the second World Cup running, Germany will suffer a humiliating exit in the group phase if they lose their Group E clash with in-form Spain at the Al Bayt Stadium. The four-time champions were left staring down the barrel of elimination after crashing to a shock 2-1 loss to Japan in their opening fixture on Wednesday. The prospect of an early German exit -- four years after bowing out at the same stage at the 2018 finals in Russia -- was practically unthinkable before the tournament. German coach Hansi Flick insisted on Saturday his team had the quality to bounce back against a rampant Spain team who obliterated Costa Rica 7-0 in their opening game. "We have a team that has quality, that can implement the things (we are working on), and we are very positive about it," Flick said.

Spain coach Luis Enrique says his team faces a "beautiful challenge" as they chase a win that will see them into the last 16. Luis Enrique cautioned however that Germany's World Cup pedigree -- they won their fourth title in 2014 -- meant nothing could be taken for granted. "They are world champions, when you look there are four stars on their shirt," the Spain coach said. "I have a lot of respect for their players, they are world-class, and their history is there to see." - Past their peak - A Spanish victory would mean Japan would also secure their passage to their knockouts if they beat Costa Rica.
