The only thing that worries me about dropping Lampard in favour of Gerrard is that Lampard is by far the more intelligent player. He is more disaplined and uses the ball more intelligently. Personally I would think of starting with the same team and if it is looking poor, dependant on who is playing the worst and what is required I would bring on one or both of Lennon or Crouch. Obvious this depends on Neville being back.
