Indeed, lessons to be learnt from this game. We should be playing Martial down the left to isolate Otamendi when we play them. Mendy did feck all defensively first half.Attacking against a 10 man, toothless Liverpool is hardly difficult.
He wasn't that impressive when Salah was on his wing. Surely he should be smart enough to drop back and give Otamendi more protection in the first half. Obiviously that's when Liverpool were controlling things and the red card changed the game, and his job in the second half has been easy.
