If anyone is wondering why the top player hasn't been signed yet, it's because we can't seem to offload Melo, Krasic, Ziegler and one of our strikers (hopefully Quags). If we can't sell these players for decent sums, the top player simply won't be arriving.
I think that especially the Melo-situation is causing the club great concern now, as I believe it was expected that he would be offloaded already.
