Goalkeeper Artur Boruc has admitted he could move on from Celtic in the summer.
The Poland international signed a new deal just two months ago to commit to the club until 2011.
However, he has been linked with the likes of Bayern Munich and Milan and he concedes he would be interested in joining a big European club.
Boruc, back in his homeland ahead of a friendly with USA, insists Bayern have not yet made an approach.
"I feel very good in Glasgow but I would like to change environment," he told the Scottish Daily Express.
"I would like to try something new.
"I don't want to leave desperately but if a good club comes along, why not?
"One report says that Bayern want me, while the other claims it is not true.
"There is no offer from Bayern.
"They are, however, a big club that I would consider if they said they wanted me."
