Chris Sutton understands Celtic frustration over perceived questionable calls in defeat to Hearts - but insists the club have their own questions to answer after confusing transfer business.

The former Parkhead striker raised serious questions over recent transfer calls at Celtic with Alexandro Bernabei and Liel Abada completing exits this week.

And that followed David Turnbull and Mikey Johnston being allowed to leave the club.

For Sutton, Abada's exit was understandable given the external factors, but Bernabei being allowed to leave with little cover at left-back is inexplicable.

In his Daily Record column, he wrote: "Why the heck have Celtic allowed Alexandro Bernabei to leave? It just doesn’t make sense to me.

"Listen, the Argentinian is no world beater. But he’s a left back. And it might have gone unnoticed at Celtic Park but that is a problem position for them."

In defeat at Tynecastle, Rodgers turned to youngster Daniel Kelly to try and help turn the game - for Sutton it was not the environment for the academy prospect. However, he admitted it said a lot about Odin Thiago Holm being left on the bench with Kelly preferred in a time of need.

He said: "Perhaps it was another message to the board – especially when £2m midfielder Odin Thiago Holm was left on the bench – but surely we are beyond that stage now?

"What got me was the fact David Turnbull wasn’t there. This is a player who was keeping Reo Hatate out of the team at the start of the season but was then bombed out completely."

Similarly to Turnbull, Johnston was allowed to leave the club despite periods of significant game time at Parkhead.

And the winger has flourished at West Brom so far on loan with a building collection of stunning strikes in the English Championship.

"You could say Nicholas Kuhn came in for Abada but he’s another one that can’t get a game at the moment," write Sutton. "And it makes it all the more galling for Celtic fans to see Mikey Johnston scoring stunners every week for West Brom, especially after they practically hounded him out."

The pundit added: "It just seems like Celtic have brought so much on themselves this season with so much confusion."
