Otamendi played with Mangala in Portugal, we have not bought him for htat sum of money to be fourth choice, he will start if Vinnie is injured.
He was covering Morratas forward run in case the ball came through, not his fault it cannoned of Kolarovs arm.
Another new CB who will soon realise Kolarov can't actually defend very well. If he simply heads the ball away, problem solved.Not the best performance but totally forgivable. It's not the ideal scenario for a debut
He cost us a point today, chased after the ball instead of holding his position when kolarov and Mangala had already gone to it.
But that's the way it goes. Can't expect him to be perfect when brought on for his debut in a game of this level halfway through.
He is a quality player, one mistake doesn't change that.
