What a load of utter shite I'm reading. He's been our best defender this year. He got trapped behind the keeper by a couple of seconds of ball watching - a bad mistake but one of very few he's made all season. Ridiculous that he's being written off on here. You genuinely think Koscielny and Mertesacker - probably the best partnership in the league - are better players individually? He's as good/better and if we find a coherent unit people will be eating their words.
