ayern Munich have refused to comment on reports suggesting Franck Ribery could sign a contract extension before this summer's World Cup.[LNB] Speculation regarding the Frenchman's future has been doing the rounds for some time, with the talented playmaker yet to commit to the German giants.[LNB]He is tied down at Allianz Arena until 2011, but Bayern have made it clear that they will look to cash in on him if he does not sign a new deal.[LNB]That admission led to reports claiming Real Madrid, Chelsea, Manchester United and Barcelona were preparing big-money bids.[LNB]However, with Bayern having landed the Bundesliga title and German Cup this season, and with the Champions League final still to come, he could yet be persuaded to stay on.[LNB]It is claimed that a five-year contract could be agreed before this summer's World Cup finals, but for now Bayern are keeping tight-lipped on the matter, preferring to give their full focus to a continental showdown with Inter Milan on Saturday.[LNB]"The club management will give no comment or declaration tomorrow or today," said press chief Markus Horwick.[LNB]"Transfer news is communicated by the management and not the journalists. We are concentrating on tomorrow's match - players, management and everybody else."[LNB]Bayern midfielder Bastian Schweinsteiger has also sought to steer clear of the issue, but admits he would be delighted to see Ribery sign on.[LNB]"These are rumours," he said. "Of course Frank Ribery is an excellent player and we'd love to keep him but if the Bayern Munich management haven't said anything, I can't say anything."[LNB]Ribery has plenty of time to consider his options, as a reckless red card in a Champions League semi-final showdown with Lyon has ruled him out of Saturday's final in Madrid.
