Brendan Rodgers must learn to stop moving Callum McGregor from his favoured midfield role.
The Celtic boss lost his first Glasgow derby on Saturday after a gutless performance at Ibrox.
With McGregor wasted at left-back, Celtic’s midfield were overrun by a rampant Rangers.
A big factor in the defeat was Celtic’s midfield being unable to hold onto the ball.
Scott Brown and Olivier Ntcham were the biggest culprits for the Hoops. The captain, who usually dominates these encounters, was extremely poor.
Ntcham was even worse, he gave the ball away time and time again and usually under no pressure.
MORE CELTIC STORIES
Ryan Christie didn’t appear to settle in his first derby start either. Celtic were let down by their big players.
Celtic’s biggest miss in midfield was not Tom Rogic as many predicted.
McGregor on current form is Celtic’s best midfielder, he should be the first picked in the team.
The champions missed his guile and presence in midfield. He doesn’t run about kicking anyone, but he puts himself about enough.
He also keeps the ball, and his use of the ball is usually impeccable. If he plays in midfield, then the inclusion of Mikey Johnston may actually make more sense.
If Celtic had more of the ball in midfield, the youngster could come and link with those behind him, much like they did against Dundee.
Moving on from disappointment
Saturday will be a tough loss to overcome, which is why the winter break has come at the right time.
It will give Rodgers time to mull over the loss and put it right in March when the sides next meet.
If he doesn’t learn anything else though, he must realise never to move McGregor out of midfield again.
