You know I am not too serious on this guys. I quite rate Kos. He really has everything to be a world class CB.
However, it is also undeniably true that he roughly averages one crazy moment per game. Not a poor decision which everybody is inclined to make, but a real potential game changer. He got punished twice yesterday and also almost gave away a peno. Lucky against Man City not to gift them a winner.
He IS a lot like Senderos in that respect...
