Celtic must make signing a new goalkeeper a priority.

That's the thoughts of former defender Charlie Mulgrew.

The Scotland cap played with a handful of top goalies during his time at Parkhead, including Fraser Forster, Artur Boruc and Craig Gordon. But the current stoppers at the club, according to the defender, are not at their level.

Vasilis Barkas has flopped since his big-money move from AEK Athens last summer, Scott Bain has been steady enough and Conor Hazard is still relatively inexperienced.

And for that reason, Mulgrew reckons whomever is next in the manager's role at Celtic must address the position quickly.

"Goalkeeper is definitely an area Celtic need to improve on," he told Sunday Mail. "The club’s had so many good goalies in the past. Whenever Celtic have been successful, they’ve always had a right good keeper. It has been the same with Rangers as well.

“In my time at Celtic, firstly it was Boruc, then big Fraser and then Craig Gordon came in and was unreal. Forster obviously came back after that and it was unfortunate when Craig left last summer.

“They brought in Barkas and it just hasn’t worked out for him. So it’s definitely something Celtic need to address. And I’m sure whoever the new manager is, he’ll look to do that.

“You need to have an established goalkeeper as your No.1. They have to make the jersey their own with performances.

“This season, it’s been so up and down with keepers and how they’ve played.”
