Nicolas Burdisso has admitted that he might have to leave Roma in order to secure a place in Argentina's World Cup squad.

The 32-year-old has not been a first team regular for the Giallorossi this season and has said that while he has an affinity for the club, he might seek a move in the January transfer window.

"I will do all I can to be part of the World Cup squad," he told reporters. "If necessary, I will even think about leaving Roma. I will decide after Christmas.

"But I am very attached to this club and the city. I have a role at Roma and the number of games I play is not the only thing that matters, even if I want to return to the Argentina side.

"Roma are doing very well this term, things are working and it's all very positive. I've been feeling in good shape since the summer and I just need to be patient."

Burdisso joined Roma in 2009 from Inter Milan.
