The club and Scolari have come out to say we're not signing anyone before, so no, I don't think we are.
We need a winger, but we may have found one in the name of Miroslav Stoch, in which case, we're fine. No, we don't need to replace Bridge, we have Ferreira and Ivanovic to cover until the summer when every player is available to us and not just certain ones. Then we can make a proper decision as to whether we think Ryan Bertrand can be Ashley Cole's understudy (or perhaps Jeffrey Bruma or Slobodan Rajkovic?) or whether we need to go out and buy a new left back.
As for Cudicini, its pretty much the same. Hilario is a decent back-up keeper. And below that we have a young goalkeeper who may also deserve a chance at the first team. In the summer is a better time to decide whether we need to sign a senior goalie (I think perhaps we will, but to replace Hilario, not Cudicini).
