Franck Ribery hasn't ruled out extending his contract at Bayern Munich.

The France international has been linked with Chelsea, Manchester City and Real Madrid and is currently tied to the Bundesliga club until 2011 and negotiations over an extension are due to take place in the near future.

"The decision is up to me," Ribery said at Bayern's winter training camp in Dubai on Wednesday.

"It is possible that I extend my contract. Why not?

"There will definitely be talks with me and my agent and FC Bayern. I think everything will be sorted before the World Cup."
