The striker made an explosive start to life in Glasgow but has since endured a difficult spell in front of goal, increasing the scrutiny surrounding his performances.

Former Rangers and Scotland defender Hutton was impressed by Hogh from his previous Champions League appearances and admits the striker initially worried him as a potential difference-maker for Celtic.

Speaking to OLBG, who offer the best betting sites , Hutton said: “As a striker, Kasper Hogh’s confidence is low. When he first signed, he looked full of confidence, buzzing about the place with a big smile on his face.

“Hogh played away against Kilmarnock at Rugby Park and I thought, ‘They've got a player here,’ because I'd seen him before in the Champions League for Bodø/Glimt and thought he was a top player.

“As a Rangers fan, you worry a bit thinking he could be a difference-maker if he hits the ground running.

“At Rugby Park, he played really well, his link-up play was excellent and he looked a real goal threat, but he's just come off it.”

Hutton questioned whether Celtic are providing Hogh with the service required to bring the best out of him.

He added: “I don't know if they aren't playing to his strengths or putting balls into the box for him to feed off.

“Scrutiny at Celtic and Rangers is huge, so when you're not scoring and the fans get on your back, your confidence takes a dip.

“Everybody knows there's a top player in there; it's just about bringing it out.”
