At Fulham Dempsey had the luxury of being allowed to drift in to the centre from the left wing, this mean't he could quite easily lose his marker (the RB) and find space between the lines. At Spurs he plays between the lines so the Centre backs know to pick him up. So essentially, he's doing the same job but in a more difficult way.
He also has the un-enviable task of playing in Rafa's old position, so a lot of the fans are expecting a technically proficient elegant footballer , and are getting grit and spit , with the first touch of a rapist.
I think perhaps now we have our silky dreamboat Lewis :holtbytongue: in the middle, Clint might be able to come on from the bench and strut his stuff from out wide when appropriate.
He could become a cult hero.
