If you read all of my posts in here, you'll notice that I AGREE that we still need better defenders and TIME. I agree with that. I disagree regarding the midfield though, we've addressed that with 3 very good additions in Di Maria, Herrera and Blind. Could we have done with another holding midfielder or box-to-box CM? Definitely. But beggars can't be choosers.
But the way some have reacted to our signings is laughable. Any supporter of any club in world football would be absolutely made up with the signings of Di Maria and Falcao. I am still on cloud 9 with it all.
As for Everton, I am discussing my feelings on you in the relevant threads. I think you are also desperate for new defenders and I don't rate Martinez as someone who can address the defensive frailties of a team well. This is why I think he'll be the perfect fit as Barcelona manager in a year or two - his teams are well known for keeping the ball and playing easy-on-the-eye tiki taka but have also always been suspect at the back.
This wouldn't matter at Barcelona because they've always been suspect at the back throughout history and usually have 80% possession stats anyway. But this isn't a luxury Everton can afford because you won't be able to bring in players of Iniesta and Messi's ilk and the Premier League is punishing if you can't defend properly, as L'pool found out last season. I am shocked Martinez didn't bring in 2 central defenders in the window and shipped out one of Jagielka or Distin. Exactly the same problem as us really except we did address it with one purchase of Rojo at CB, plus we now have far better striking options.
