Celtic manager Ronny Deila has told The Scottish Sun that Dedryck Boyata's performance against Molde was 'not good enough' - and claims the defender agrees.
Boyata, 24, joined Celtic from Manchester City over the summer, replacing his compatriot Jason Denayer in a re-tooled Celtic defence.
However, the Belgian has struggled to really hit top form yet, which is understandable considering how little football he has played in recent years.
Against Molde in the Europa League on Thursday, Boyata was guilty of turning his back to the ball, which enabled Mohamed Elyounoussi slammed the ball home from the edge of the box.
Boyata's defending prompted unimpressed responses from Celtic fans, and now manager Deila has joined in the criticism of the centre back.
Speaking to The Scottish Sun, Deila admitted that Boyata's defending against Molde simply wasn't good enough, and also believes that Boyata himself will agree with that verdict - but backed him to improve alongside fellow new signings Jozo Simunovic.
"I think he agrees that’s not good enough," said Deila. "But you have to see also that Boyata hasn’t played regularly for many years and has now played for three or four months. He is in a learning process. When he and Jozo Simunovic have played together, you can see that he’s more determined too."
"Many things happened at the first goal. It goes wide and Stefan Johansen goes out, so Kris Commons has to take his place. He doesn’t do that. Then there’s the clearance, Dedryck should be closer. The other goal, a long pass to the back post, was way too easy. We also got run off at the far post," he added.
Given Simunovic's injury problems, Boyata is likely to play against Ross County on Sunday, where he will be given an opportunity to atone for his error against Molde.
