Roy Keane questioned the injury that kept Cristiano Ronaldo out of the Manchester derby, insisting something "doesn't add up" after Ralf Rangnick's comments on the absent Manchester United superstar.
The Portugal star was omitted from the matchday squad that travelled to the Etihad to face Manchester City on Sunday.
Rangnick provided an update on Ronaldo's condition before kick-off revealing he had problems with his hip flexor on Friday and wasn't able to train.
