I've seen him track back once.
He rejoins the offensive play too slowly.
His single talent is to receive the ball, totally stop our forward momentum and speed of play and then pass it either sideways or backwards to a midfield option; indeed this is what Mahrez basically does 99% of the time and it is woeful.
He may occasionally cut in (of course he does, he's hugely left-footed on the right wing) and does something greedy like take a ridiculous pot shot into Row Z.
He isn't quick.
He can't beat an egg, let alone his man.
I've had enough of watching him and the list could go on and on. All managers make mistakes and have blind spots, Mahrez is Pep's. His price tag puts him as ou most expensive player in our entire history, which is laughable but a function only of the market not his ability. A terrible signing and I cannot understand anyone defending Mahrez given the miserable contribution he has made. He ruins our attack, plain as day. I listen to all the City podcasts and the Ian Cheeseman one has some lad on there setting out his case that Mahrez has an 'unbelievable first touch'. No, Bernardo and David have that, Mahrez doesn't. I am not sure what he has as we haven't seen anything special or even remotely approaching decent, in my opinion. Sure it's all about opinions but I have found myself eating my own fingers with this guy and it's not just petty stuff. How pep didn't remove him at HT last night is beyond me, he was having another...another...crap pile.
After the ball was centred, after the whistle blew...
