When he plays in the supporting striker role, he ends up playing with his back to goal, far too often. Which is far from his strength.
There is a very good argument to suggest that Rafa will continue to use him on the right in at least half of next season's games.
Money should be spent on a striker, or strikers.
I wouldn't be surprised to see Gonzalez or Kewell start on the right next season, if Gerrard does not. And before Rashid says "but Gonzalez is a left winger," so is Robben, and Duff for that matter.
