Frank McAvennie has tipped Celtic to sign another centre-half this summer but does not think such an arrival would facilitate Kristoffer Ajer’s exit.

The former Hoops and St Mirren striker, speaking exclusively to Football Insider correspondent Dylan Childs, expects Neil Lennon to have words with the 22-year-old in a bid to keep him at Parkhead this summer.

Lennon admitted yesterday that “every player has a price” just a week before the English transfer window opens.

Football Insider revealed at the end of May that the club would be willing to sell Ajer if their £20million asking price was met.

McAvennie echoed Lennon’s comments and conceded that all clubs in Scotland are selling clubs.

“You are only as good as what people pay for you,” he told Football Insider.

“At the moment I think Ajer and Jullien are good players but they need to be pushed. They need to bring another centre-half in which I have heard they are going for.

“Ajer is a player that is comfortable coming out of the back with the ball but sometimes it is a nightmare to watch him do it as a supporter.

“I would give him a talk and say, “Stay here another year and then you can go.” But Scottish football is a selling place now, sadly.”

Lennon said: “Ideally we don’t want to sell our best players and we will remain steadfast on that.

“But if an offer comes in then I’m sure the club will consider it and do the best thing possible for the club going forward.”
