Brazilian midfielder Diego has been fined by Wolfsburg for storming out of the team hotel before a crucial relegation battle at Hoffenheim on Saturday.
Diego skipped the match and returned to training Sunday, when Wolfsburg coach Felix Magath said ''he has a contract and apparently realized that obligations must be fulfilled.''
Magath told Sky on Saturday that Diego - a ?15.5 million ($22 million) purchase from Juventus - reacted badly after being told he would be starting as a substitute.
Wolfsburg won 3-1 without the 26-year-old to ensure Bundesliga survival on the last day of the season.
Magath said ''he gave no explanation.''
Diego, who has a contract with Wolfsburg until 2014, said: ''It's my problem, our problem. We have to sit down together and find a solution.''
Magath suggested the Brazilian may be given another chance. No details were given of the fine.
''It doesn't interest me if someone makes a mistake. I'm ready to work with anyone, but it has to be evident that they'll do things my way,'' the 57-year-old said. ''Everything is possible.''
