Kristoffer Ajer has come under fire from Celtic fans on Twitter.

Kristoffer Ajer hasn’t been at his commanding, assured best for Celtic since the return of Scottish football last month.
The Hoops went to Dubai for a warm weather training camp during the winter break and it seems like the towering centre-back hasn’t recovered his form from the first half of the campaign.
In the win at Hamilton last weekend, for example, the Celtic defender made a hash of a routine header in an error which led to the hosts almost taking the lead, before they eventually did.
And in tonight’s victory away to Motherwell, the Norway international was found wanting yet again.
Not only was Ajer guilty of dodgy positioning at times, but his ball-playing qualities seemed to desert him on occasion, leading to a number of stray passes.
Celtic picked up a 4-0 win nonetheless, but Ajer’s form is becoming a worry and here’s how fans of the Parkhead club reacted on Twitter:
Odsonne Edouard’s strike on nine minutes gave Neil Lennon’s side a slender advantage at the half-time break.
Celtic steamrolled the Accies in the second half on Sunday and the same happened at Fir Park, with Leigh Griffiths, Callum McGregor and another from Edouard giving them a four-goal lead.
