Because hes been constantly hyped up to be a magnificent, world-beating player who is better than Messi and Ronaldo in the press for the past few days and hasnt delivered anything. For a player with that much hype you expect something - which didnt deliver so hes rightly being ripped for it -...
May have an England cap now, but with a performance like what ive heard* - its probably dropped a bit.
*= Havent actually seen the game as Masterchef was on and that was better so im going by what is on Twitter and NSC.
