Yes but you can take him off if he's playing, which I think Pep should've done after an hour, before risking a bad tackle or even a freak incident, if he had that incident in the first half fair enough, but it was in the last few minutes when he shouldn't have been on the pitch, get him off while you can.You don’t consider tripping over flat grass whilst jogging a ‘freak incident’?
There’s every chance he does that in the warm down or on the 4g walking to the bench.
If he’d have overstretched a groin or hammy I tend to agree. But not for a stumble on grass. The guy likes scoring you know.
