Chelsea midfielder Michael Ballack accused Portsmouth's Kevin-Prince Boateng of deliberately trying to injure him after a tackle which left the Germany captain a slight doubt for the World Cup finals this summer.
Ballack had to leave Chelsea's 1-0 FA Cup final victory over Pompey just before half-time following a reckless challenge from Boateng.
Boateng, who missed a second-half penalty, was shown a yellow card by referee Chris Foy, but Ballack was adamant the Pompey player meant to harm him.
"I am more worried about my injury now," said Ballack, who left Wembley with his right foot in a protective boot.
"I have seen it on TV and to say it was not on purpose means you have to be a friend of Boateng.
"Boateng was lucky to get away with a yellow but it is football and if the referee controls the game and decides it is no red card you have to accept it.
"I can walk on it, not quite comfortable but I can walk, which is not the worst thing. I don't think there is a break.
"We will have to wait until tomorrow to have a scan, then we'll know more. Hopefully it won't stop me playing in the World Cup.
"I couldn't carry on but I hope it's not too bad. Injuries are not good but there is a little time to go yet until the World Cup."
Ballack was still delighted to be part of a Chelsea side which lifted the League and FA Cup double for the first time in the club's history.
"It's great," he said. "It's the first time in Chelsea's history so everybody is so happy about what we have achieved in the last week.
"We have won two titles and we have put in a lot of effort.
"Carlo (Ancelotti) is the coach and he has the responsibility for everything. He prepares for games well and gets us training every day.
"It's like the team is his handwriting now. We have scored lots of goals and he's a great manager. The fans love him, and rightly so if you win two titles in your first season."
However, Ballack still does not know if he will be a Chelsea player next season. His contract expires in the summer and the club seem reluctant to offer him the new two-year deal he craves.
"I don't know what will happen," Ballack said. "I will go and talk to Chelsea but at the same time I have to think about the World Cup."
