Celtic defender Kristoffer Ajer is almost certain to accept an offer from Newcastle United – and pave the way for a “massive move” down south. 

That is according to ex-Premier League goalkeeper Paddy Kenny, speaking exclusively to Football Insider after the Scottish Sun reported that the Magpies have stepped up their interest in the 23-year-old centre-back.

Newcastle scouts are understood to have watched Ajer feature in Celtic’s defeat to Rangers last Sunday.

Ajer enters the final 12 months of his contract in June and has long been linked with a move away from Celtic Park.

And Kenny urged the 21-cap Norway international to act now if he wants to seal a dream Premier League move.

“It all depends on how ambitious he is,” he told Football Insider correspondent Adam Williams.

“No disrespect to the Scottish league but if he’s got the chance to come and play for a team like Newcastle, I’d be surprised if he turned it down.

“Joining Newcastle, it’s a massive move. You want to play in the Premier League, test yourself week in, week out against the best players.

“If he gets that opportunity, I don’t think he’d turn it down. It might be his only chance to come to the Premier League.

“If he does turn it down, that move might not come around next year. It could be too late. You’ve got to take it while you can.”

Ajer has featured 44 times for Celtic this season and 174 times in total for the club.

A converted midfielder, Ajer signed from Norwegian side IK Start in 2016.
