Lampard obviously won't fix all that is wrong with our team, we aren't a perfect team nor do we have the budget to be a perfect team, Lampard won't come and make us a world class club. Its also way too early to say Lampard won't make us significantly better or fix a lot of our weaknesses, because well we don't really know our own weaknesses yet. We have played 1 competitive game and got a draw in-front of of 65k fans, not exactly a bad result.
Summer transfers are tricky though, so hopefully Lampard and DP3 work out. Last season New England wasn't anything special at all, and then in the summer they added Jermaine Jones as a DP and he made them the best team in the East, so hopefully we get that effect!
