In my post, I said that's the only thing he is bringin to the table, but people like you still hate him so much, you need more. His first touch is the reason why he scored last match, a goal that no one in our team would probably make(bar Haaland maybe?). Does that mean he should be a starter? Of course not. He should be our 5th option(which he is right now). But still, I can see the things he does well.
He is our 2nd best penalty taker, not because he is great at them, but everyone else is even worse, so I did not care about the penalty miss.
Like I said, he cannot dribble anyone and never goes forward and it is a liability right now. Still Pep is doing the right thing. Try to involve him into easy matches to see if he can recover form. Our team against elite competition will not have Mahrez in it, but we still need him to be involved to rest key players.
