I'll answer this, for the MILLIONTH time the same way I always do.
Could Frank Lampard have helped Liverpool win the CL's and keep them up in the top 4, like Stevie G has.
I really don't believe he could have.
But Steven Gerrard in the Chelsea side, I doubt very much Man united would be level with Liverpool on titles at the moment.
In Europe, this is not even an argument, Lampards a respected play, but Gerrard is a notch above.
