Apparently, Arsenal after him for 10 mil. If we sell Masch, I think he would be perfect for us. I'd go as high as 15. Our set piece issues would be eliminated. Also a pairing of Mertesacker and Agger would tick all the boxes (apart from blistering pace). However, he looked solid for Germany next too Friedrich who is not massively fast. He also played well next to Lahm who loves to get forward. I'd even offer Skrtel as part of a swap.
75% of our games in the prem will be against teams that will attack through the air or at set piece. He also scored 5 goals in the league last year. We need to build from the back.
