Good player and he and Kompany's partnership were the key last season. Nastasic is an excellent player but the understanding with Kompany is just not the same. He is a very much left footed, LCB so doubt it would work with Agger. Isnt it funny how 2 right footed centre halves are fine but 2 left footers seem weird? My guess is he is going to Arsenal this summer with Vermaelen heading to the Nou Camp, great value though!
