Frank McAvennie has tipped Neil Lennon to drop Kristoffer Ajer for this weekend’s trip to Ross County and hand new signing Shane Duffy his Celtic debut.

The Parkhead legend, speaking exclusively to Football Insider correspondent Dylan Childs, claimed that 6ft 4in centre-back Ajer, 22, had “dropped the ball a bit this season” and his position in the team is under threat from the arrival of Duffy.

The club confirmed the signing of Shane Duffy on a season-long loan deal from Brighton earlier this month and the centre-half is expected to be a regular starter for the Hoops.

He could make his debut on Saturday as Neil Lennon’s side travel to Ross County which could come at the expense of either Kristoffer Ajer or Christopher Jullien.

The two have been the undisputed defensive partnership at Paradise but the arrival of Duffy casts doubt over both their positions if Lennon continues to play four at the back.

When asked by Football Insider who he thought would make way for the Republic of International, McAvennie said:

“I think that Duffy will play with Jullien, to be honest with you.

“Ajer has dropped the ball a bit this season. Listen, it is competition and that is the most important thing.

“Duffy has come in and if Ajer is the one that gets left out if he has anything about him he will roll his sleeves up and try and get back in there. That is what being a footballer is all about.

“Bitton can play beside Duffy as well because he likes to play. Duffy likes to go and win the ball. That was a problem before so I am delighted they have got him in.”

In other Celtic news, Frank McAvennie has told Football Insider that he is “absolutely delighted” by new signing’s reveal, which is break for the norm.
