Lampard and Gerard can play together, there is no doubt. The question is wheather you get the best out of either of them.
Do they hesitate for a second to see if the other is covering them, at there clubs they don't have to do this and is why they are so successful.
As much as like Joe Cole, if a midfielder wa to make way it would be him and the team would play 4-1-3-2 with Carrick or Parker in front of a Gerrard, Lampard, Beckham midfield, relying on the full backs to help out wide. Its not like Cole or Beckham are "wingers", they spend most of there time cutting inside.
But I am happy with the way things if they stay that way
