Here are Celtic's player ratings after their 2-0 defeat to Rangers.
Barkas
Huge error for the opening goal, should have easily dealt with Connor Goldson's header. Didn't have much chance with the second, but doesn't com mand his area effectively. Looks a huge downgrade from Fraser Foster. 4
Welsh
Composed performance considering it was his second game for the Hoops and he was thrown in at the deep end at the eleventh hour. 6
Ajer
Sloppy distribution in the first half and struggled to deal with Ryan Kent dropping deep. Fouled the winger for the free kick that led to the opener. Then again the Norwegian stopped it from being a blowout with two key last ditch blocks. 6
Duffy
Labored on the ball and didn't really get up to the speed of the game. Alfredo Morelos successfully got under his skin. Poor on the ball too. 5
Frimpong
Could be his worst performance in a Hoops shirt as he offered nothing going forward and was caught out at the back on a few occasions. 5
Laxalt
It was a decent debut for the left-back, but nothing spectacular. Bright in the first half and was at least looking for the ball unlike most of his team-mates, just didn't get much help from them. 6
McGregor
Some nice touches early on, but was outplayed by Glen Kamara and Scott Arfield. Wasn't helped by Olivier Ntcham or Scott Brown, however. 5
Brown
Barely laid a glove on the Rangers midfield and didn't really offer anything else. 4
Ntcham
Absolutely lost this season. Not the Olivier Ntcham Celtic fans are accustom to seeing. Taken off in the second half and rightly so. 4
Elyounoussi
Celtics' best player in the first half and was unlucky to be the one who was taken off. Missed a glorious chance, however, as he blazed over a chance at 1-0. 6
Klimala
A poor day at the office. Couldn't string a pass together and rightly hooked early in the second half. 3
Subs:
Ajeti
Difficult for the striker to make a mark after his recent hamstring issues and didn't make much of an impact. 4
Rogic
Didn't offer much when he came on late in the second half. 3
Griffiths
Had Celtic's best chance of the second half as he rounded Allan McGregor, but his touch was too heavy. Wasn't provided with much service. 5
Turnbull
On late, but the game was all but over. 3
Taylor
Strange sub as the Hoops looked to get back in the game. 3
