Celtic chief executive Peter Lawwell admits the club is prepared to let Fraser Forster leave provided they get the right transfer fee for him.
The 25-year old English goalkeeper is reportedly attracting the attention of the likes of Barcelona, Manchester United and AC Milan with Lawwell suggesting he could be sold for the right price.
"These things sort themselves out," he told the Daily Record.
"If we're bringing players here to develop them and get in the Champions League and they do well, England is down the road.
"If we are offered the right fee, we will take it and reinvest in another keeper or another centre forward or another midfielder."
Lawwell added: "Also within that equation, if a player is trebling or quadrupling his wages, then it's an easy decision for him.
"So there's no real friction preventing that happening. The player is happy, the club, for the right fee, is happy and the buying club are happy."
