Jackie McNamara admits he is astonished to hear that Celtic goalkeeper Craig Gordon could hang up his boots at the end of the season as the shot-stopper weighs up his future as a footballer.

The former Celtic and Scotland defender, speaking exclusively to Football Insider assistant editor, says that the 36-year-old is still has a couple of years left playing at a decent level, heralding his ability to come back from a serious injury earlier in his career.

As revealed by Football Insider, the 54-cap international is considering spurning the chance to move clubs when his Celtic contract runs out next summer and instead call time on his playing days after 432 first-team appearances at club level.

McNamara says he would be taken aback if the giant keeper, who stands just short of 6ft 4in tall, were to call it a day, insisting he could still do a job for a couple more years at a high level.

McNamara told Football Insider: “Obviously he’ll know what he wants to do, he’s done great after his injury, he’s come back from injury and he’s still relatively young in terms of a keeper.

“He missed a wee bit when he was at Sunderland with injury and came back really well in fairness to him. He managed to come back so there’s talk of him finishing but I’d be very surprised, he’s still maybe got a few years left.

“I think he’ll want to play, like everybody else. Goalkeepers in that position are relying on the other keeper getting injured, a loss of form or getting dropped or suspended. It’s not like an outfield player where there’s injuries, it’s a lot tougher to get in.” 

Gordon has a total of 241 appearances under his belt during his time at Celtic Park, although only five of those outings have come in the 2019/20 campaign thanks to the arrival of Fraser Forster and Scott Bain in recent years.

He has picked up five league trophies, four Scottish Cups and four Scottish League Cups in Glasgow, playing a crucial role on the way to their first of three consecutive treble-winning campaigns.
