I think its a case of we couldn't let the opportunity to pick up KKH go, especially at the price we paid for him, which is very cheap considering his pedigree.
We got very lucky last season with MvE being available for virtually every game, but there were times when his form dipped and he needed resting, and Eccles or Lats are definitely not the answer if he gets injured.
Having said all that, no one would be suprised if he were to be sold, and £8m would definitely do the trick.
