Hello, i am new here, but i have a big question, why isn't Per Mertesacker sign for man utd yet, isn't he one of the underrated CB in the world? i am a Utd fan and keep wondering that when Rio retired, it will be up to Vidic and J.Evans to secure the back line but with Vidic aging......
anyway, is it because Per Mertesacker is injury-prone, too much weakness or the adaption of the English game?
please, i want to hear your thought..
