Celtic have included a clause in Fraser Forster’s loan that would allow the Hoops to sign the goalkeeper on a permanent basis next summer, according to the Evening Times.
It was initially thought that the 31-year-old had joined the Scottish champions on a straight loan deal, but it appears a transfer fee has also been agreed with Southampton for the shot-stopper if Celtic want to sign the player in July.
However, there appears to be one major obstacle to Forster returning permanently to Parkhead. His wages are likely to be way above what the Hoops can afford.
The keeper signed a new six-year contract with the Saints back in 2016 to ward off potential interest in the player, seeing him earn £70,000 a week.
Celtic would not be able to afford such a salary so it will be up to Forster to accept a major pay cut if he wants to secure a move back to Scotland.
