Former Celtic goalkeeper Andy Walker believes Fraser Forster will sooner or later make the move back to England.
Forster has been in fine form for the Hoops this season, keeping 12 straight clean sheets in the league, prompting suggestions that he may move on in the summer.
Sky Sports pundit Walker, who played for Celtic in the late 1980s and in the '90s, believes the day will come when Forster follows the footsteps of Hull City's Allan McGregor (formerly of Rangers), Cardiff City's David Marshall (previously with Celtic), Newcastle United's Tim Krul (loan with Falkirk) and Crystal Palace's Julian Speroni (from Dundee).
"Allan McGregor, David Marshall, Tim Krul and Julian Speroni have all played in Scotland and have gone on to bigger and better things," he told Sky Sports.
"I'm sure Fraser will probably move on from Celtic pretty soon and I have no doubt he will do a good job at the top level down there."
Of Forster's hopes of making England's World Cup squad, Walker added: "He has great ability and I know there is talk of whether he should be in the England set up.
"I'm sure Joe Hart will be the first choice for Roy Hodgson in the summer but if Forster was given a chance, I don't think he would let anyone down."
