Carl Starfelt has had a poor start to life at Celtic – culminating in his first goal for the club being an own goal for Alkmaar in the Europa League.

The Swede’s mistake brought me back to Ange Postecoglou when he first came into the club. The Hoops boss was not concerned about mistakes being made, what he wanted to see was the resilience and the character to come back from a mistake – get the head down and keep going.

I think we got a second half performance out of Starfelt that was lacking in the first.

The centre-back is the oldest player in defence and was flanked by three academy players this evening. It will not be easy to bed into that sort of environment and play the sort of expansive football the manager is looking for.

The mistake tonight was horrendous, let’s not sugar coat it. The centre-back gave Alkmaar a massive shot in the arm and it could have been fatal, but vitally, it wasn’t.

Carl will have to convince the most critical of fans he’s up for the task. His character tonight in the second half and his resolute defending gives us something to cling to.

You can’t have too many of those howlers in a Celtic jersey before the fans will be on your back. Carl must regroup and if he can put in a solid performance at Ibrox, he will start to change some minds.
