Kewell made all the difference last season in the prem, defenders were scared of him and he could put quality balls in the box and linked superbly with Riise. He's the reason why Gerrard could drift so many times inside from the right, Alonso could always spray the ball out left to Kewell so the defense was stretched anyways. Although perhaps decent squad players, Gonzalez and Pennant will never reach the standard we're looking for in a winger, for me they don't do enough and I wouldn't be surprised if either one gave place for Adam Hammill on the bench next season if we brought in a quality winger.
