Ally McCoist believes Aberdeen target Scott Brown is good enough to remain at Celtic for another season on the evidence of his eye-turning display against Rangers.
But the Ibrox icon admits the legendary Parkhead captain might be exiting the club he has served for 14 years at the right time ahead of a rebuild on and off the park.
Stephen Glass was named the new Aberdeen manager on Tuesday and Record Sport revealed Brown is set to follow in an assistant manager-player role.
McCoist believes the pairing has the potential to reap rewards in the Granite City as Dave Cormack craves an exciting brand of football in the wake of long-serving Derek McInnes' departure.
Speaking to talkSPORT, he said: "It's an interesting one because I thought he played really well at the weekend.
"Clearly, on that form, you could probably say he could have another year at Celtic.
"I remember a couple of years ago there was talk of him going to Australia, nonsense like that, he had for too much to offer.

"I still think he still has a good bit to offer. I haven't spoken to Scott but I think he maybe now fancies playing but at the same time moving into a coaching capacity.
"I know he is friendly with Stephen Glass, they were team-mates (at Hibs).
"I think is a natural progression in his football career, the timing of it, only he could answer if it's right, it certainly wasn't right going to Australia two years ago.
"On current form he could probably play another year for Celtic but there is going to be vast, vast changes in the personnel and maybe Scott feels the timing of the potential move to Aberdeen will be perfect for him."
