Celtic boss Neil Lennon has admitted that young goalkeeper Fraser Forster could join a huge club in the January transfer window if a bid comes in for the player.

Reports this week have suggested that the likes of Manchester United, Arsenal and Barcelona could be interested in bidding for the keeper's services.

"It's going to be impossible to keep Fraser, the way he's playing," said Lennon, according to The Metro.

"Inevitably, I think a huge club will come in and make a huge bid for him.

"Sometimes it is frustrating as a manager, as you are trying to build something, trying to progress the club, but I think it is a huge compliment that big clubs want out players."

Forster has been in impressive form in both the Scottish Premiership and Champions League this season, with the keeper trying to force his way into the England squad.
