Celtic chief executive Peter Lawwell has revealed that the Scottish Premier League club would be willing to sell Manchester United and Barcelona target Fraser Forster 'for the right price' in January, reports Sky Sports.
The England international goalkeeper has been the subject of intense transfer speculation in recent months, following a number of inspired performances, both domestically and in Europe this season.
Red Devils boss David Moyes has been credited with an interest in bringing Forster to Old Trafford, to provide competition for current Red Devils first-choice stopper David De Gea.
The 25-year-old impressed when he faced Barcelona in the Champions League at the beginning of October, with his outstanding double save from Neymar and Alexis Sanchez catching the eye of Gerardo Martino.
Forster has since been linked with a move to Camp Nou, as the Catalan club continue their search for a replacement for Victor Valdes, who will leave Spain when his contract expires at the end of the season.
Both Manchester United and Barcelona have been offered hope in their respective pursuits of the Celtic stopper, after Lawwell intimated that the Bhoys will not block Forster's move when the transfer window reopens, despite the fact he's played an integral role at Parkhead in 2013/14.
"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 that Celtic are also unable to compete with the sort of wages on offer at the likes of Manchester United and Barcelona.
"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.
"No matter what we do, there is a realisation that in a very short period of time, the next-door market can pay huge amounts of money that we could never compete with."
