I'm surprised Coutinho hasn't been mentioned yet. Relatively cheap and is capable of being a very, very good player. Perhaps in a couple of years he will stroll onto this list.
From what I heard his account had been dormant for a year or so and things disappeared from his page. Could be time controlled removals, orders, anything. I may be wrong but I don't think there is much to this.
It's difficult to be certain but Newcastle were a great team under Keegan when we played out the famous 4-3 win with Collymore scoring the winner. Keegan and his players seemed effected for a while after this.
In 2005 Liverpool lost 0-1 to Sao Paulo in the World Club Championship. How many times did Liverpool put the ball in the opposition's net, only for them to be disallowed for offside? Xavi?
