He did not do well at all. His positioning was atrocious and he kept keeping Sunderland onside on 3 occasions with poor decision making and not knowing when to play offside. Hell even Kaboul had a go at him half way through the game.
Fair enough I forwarded through parts so I probably missed that. But those things are understandable for me. First time he's probably played with Kaboul. Centre back pairing is all about understanding and a solid relationship. The mistake is unforgivable, but I am generally impressed with Chiriches
