Celtic defender Kristoffer Ajer

Celtic need to prioritise the signing of two centre backs this summer with Kristoffer Ajer set to leave. 

That’s according to former Hoops hitman Frank McAvennie, speaking exclusively to Football Insider after a reported transfer update.

Last week, Italian journalist Nicolo Schira claimed that Celtic have had a £4.3million bid turned down for Hajduk Split defender Mario Vuskovic.

Stephen Welsh, 21, and Ajer have been Celtic’s defensive pair of choice in recent games after Welsh was handed a new four-year deal in April.

McAvennie slammed Ajer for not helping Welsh as a more experienced player and claimed that he needs to be replaced because he won’t be at Parkhead next season.

When asked if strengthening the centre back position with players like Vuskovic is a priority for Celtic this summer, McAvennie told Football Insider correspondent Ben Wild, “Oh god, definitely.

“I think they need at least two to be honest with you, the boy Welsh has a new contract and he could turn into a good player. He’s got an awful lot to learn but he could be decent. 

“Ajer is going to be going this summer, he’s gone. That boy [Vuslovic] could be a replacement. He’s not helped Welsh out at all, he’s just looking after himself. 

“Celtic need two centre-halves this summer so I would not be surprised if a bid has gone in at some point.”

Ajer, 23, has been a mainstay for both Neil Lennon and John Kennedy this season, making 43 appearances so far.

Ajer and Welsh could find themselves at the heart of Celtic’s defence once again this weekend when they travel to Ibrox looking to end Rangers’ unbeaten league record.

In other news, McAvennie is gutted that one senior Celtic player could quit the club this summer.
