It didn't seem to hurt Cristiano Ronaldowith Dom apparently maybe becoming injury prone.
i think it could be him over doing the fitness thing.
those pictures of him after the Crystal Palace match were he looked ripped as f. while maybe being pleasing to the eye when he strips off to do a photo shoot and boosting his self image, its not necessary or advantageous to be over-ripped
when you get really ripped and fine tuned you`re more likely to get injured.
