While the Polish international appears happy to stay in Glasgow, Euro 2008 could offer a perfect stage for Boruc to showcase his talents.
"According to the press, I've already signed for AC Milan, Manchester United and Chelsea - but I'm still in Glasgow," Boruc said.
"I'm still a Celtic player and know nothing about any offers.
"However, as I've said in the past, should an offer arrive from one of the top clubs, I could try it."
