What the Hell are Liverpool Doing paying 20 Million for Henderson?

The money paid is absolutely way over the top. I didn't need to see his England performances. My mackem friends have been dancing in the streets cos they can't believe he's been sold for that amount of money. They saw him every game and they say after a good start he faded badly once other teams sussed him out. Good engine, but weak, slow, doesn't create or score goals, can't cross and can't tackle. That's not my opinion, it's the opinion of Sunderland season ticket holders I know...
