Former Celtic striker Frank McAvennie has exclusively told Football FanCast that he believes defender Kristoffer Ajer wants to leave the Parkhead side this summer.

He's contracted until the end of next season, but has been told to quit by Norway manager Stale Solbakken in order to challenge himself in one of Europe's top five leagues and improve on the international stage.

Ajer has been with Celtic for four seasons and has been a regular under both Neil Lennon and John Kennedy this term, starting all-but two of their Scottish Premiership matches, plus five of their six Europa League games.

However, the Norwegian has already been linked with an £8m move to Newcastle should they avoid being relegated, and McAvennie appears to believe that Ajer's future lies away from Glasgow.

McAvennie has previously slammed Ajer for his comments about this being his best season at the club, and has blamed him for part of Celtic's defensive struggles.

He told Football FanCast:

"I think Ajer has made it clear that he wants to go.

"His Norwegian manager has made it clear that he's got to go - he seems to think that Scottish football is not doing him any good. 

"It's not doing him any good because they're letting in goals. It doesn't take Einstein to work out that it's the defence's fault."
