Gilberto Silva is keen to represent Brazil at the Olympics this August, a move that would rule him out for the start of next season at a time when his Arsenal future is already in question.

Brazil coach Dunga has shown greater faith in the World Cup winner and may select Gilberto as one of three over-age players for the Beijing Olympic tournament, which finishes on 23 August.

'It would be great to represent Brazil in a competition that I've never played in before and the only competition that Brazil never won,' Gilberto said. 'If I'm one of the players Dunga wants to bring it would be nice to be there. I will do everything to help but I don't know if the club will allow it.'

By the time of the Olympics, the 31-year-old could have new employers, although he has yet to receive a concrete offer from another club.

'Nothing is definite yet,' Gilberto said. 'At the moment I don't have anything - no offer from any club - and I don't know if Arsenal have received something. The only thing I can say is that I will make a decision at the end of the season.'
