A former Aberdeen chief reckons Brendan Rodgers is working on 'borrowed time' at Celtic.

Keith Wyness has aimed a pop at the Irishman, seemingly out of nowhere, as he insists the Parkhead board should be looking to make a managerial change.

Rodgers returned to Celtic last summer as Dermot Desmond got his trusted man to replace Ange Postecoglou.

It's not been as plain sailing as his first tenure though, with an early League Cup exit to Kilmarnock and a poor European campaign only saved by a seven-point gap over Rangers. 

However, that's now been wiped out by Philippe Clement's team who sit top of the pile in the Premiership - two points ahead of the champions.

Celtic will play Aberdeen in the semi-finals of the Scottish Cup next month. 

And ahead of that game, Wyness - who was Aberdeen's chief executive between 2000 and 2004 - has been heavily critical of Rodgers.

He told Football Insider: “I wouldn’t be surprised to see a change in manager in the off-season. I don’t know if Rodgers was the right pick. It’s not a happy ship.

"It does seem to be on the pitch where the failings have come. It certainly seems that they’ve been underperforming in some pretty key games.

“If you’re not first in Scotland, you’re nowhere – and I think the footballing side is what I’d be focusing on to find answers. I don’t have any sympathy for Rodgers. He’s a very experienced manager and he knew what he was walking into.

“That was part of the charm for him. I think he’s running on borrowed time. It’s going to be very hard to claw it back after this unhappy start. Even if he wins the league, I think it will only be a year or two before he ends up leaving.”
