Derek Johnstone believes there is no reason why Allan McGregor cannot continue playing for Rangers until he is 40 years old.
Rangers snapped McGregor up during the summer transfer window and the 36-year-old has dislodged Wes Foderingham as the Gers' number 1 between the sticks.
The Scotland international has been in inspired form for Rangers and turned on the style in the Europa League in midweek as he helped the Gers earn a 0-0 draw against Villarreal.
Rangers legend Johnstone is thrilled with the impact McGregor has had and thinks the goalkeeper, who will turn 37 years old in January, does not have to hang up his gloves for a good while.
"The day you go in and you don’t give your all and you don’t learn anything, that is the day that you chuck it", Johnstone wrote in his Evening Times column.
"Thankfully for Rangers, Allan is nowhere near that stage.
"He is in great shape and who is to say he couldn’t go on and play until he is 40?
"Keepers have done it before and there is no reason why Allan couldn’t play well beyond his current contract with Rangers.
"If you are a goalie at Rangers, you can’t help but learn from someone like Allan and they will all be loving the chance to see how he works.
"But the task of getting him out of the team looks almost impossible right now."
Foderingham has been relegated to bench warming duties due to McGregor's fine form and has been linked with an exit from Ibrox in the transfer window next month, with Leeds United mooted to be keen.
