Franck Ribery has urged Bastian Schweinsteiger to commit his future to Bayern Munich amid interest from abroad.
Schweinsteiger is out of contract in 2012 and Bayern are hoping to persuade him to sign an extension, but the Germany midfielder warned during the summer that he was "not married" to the club and could be tempted by a move abroad.
"I hope he can sign up until 2015, as I did," Ribery told Bild. "I have a great relationship with him. He has developed into a world-class player.
"Players like him are extremely important to further progress in European club competitions. If he asks me, I'll immediately say, 'Stay with Bayern, Basti!'"
Schweinsteiger recently expressed an interest in moving to the Premier League, with Manchester United and Chelsea reported to be among the interested clubs.
"I love the kind of speed of the English game but I don't know what will happen with me," Schweinsteiger said in the Sunday Times. "I have a contract until 2012 and we'll see.
"What I love is the atmosphere in English stadiums. When we played last year in Manchester, it was fantastic. My brother is a big fan of Man Utd and he always says, 'Go to Man Utd, go to Man Utd.' I say, 'I can't, I can't'.
"For me, in England the fans are better. When the team give their best, they are not booing. It's more like they are fans more with the heart."
He added: "I watch the English games on TV and I like the Chelsea style at the moment. They're very strong."
