AC MILAN are reportedly plotting a summer swoop for Kristoffer Ajer as part of a £75million spending spree.

The Italian giants this week appointed Ralf Rangnick as their new manager and the German will be given significant spending money ahead of the new season to strengthen his squad.

The Scottish Sun report that Celtic star Ajer is one of the top priorities on Rangnick's shopping list.

The Norwegian still has two years left on his Parkhead deal so it is understood that Milan would have to offer over £20million to have any chance of signing the defender.

Ronny Deila brought Ajer to Celtic for just £650,000 in 2016 when he joined from Norwegian side IK Start.

He then went on-loan to Kilmarnock before becoming a regular under Brendan Rodgers.

Last season he struck up a strong partnership with Christopher Jullien at the heart of the Celtic defence.
