Manchester United interim manager Ralf Rangnick insists he has no reason to dispute the cause behind Cristiano Ronaldo's absence for the 4-1 thrashing by City and insisted it would be unhelpful to be 'frustrated' by the continued absence of Edinson Cavani.
Ronaldo, 37, was driven home from training on Friday due to an issue with his hip flexor that ruled him out for two games against Aston Villa in January and did not train on Saturday.
Cavani, 35, has missed the last six games with a groin problem but had been declared fit by Rangnick on Friday. Cavani played one game in nine at the same stage last season, when the Manchester Evening News first revealed United's frustration at Cavani's tendency to declare himself unfit for games.
