Not everyone is Evra and Vidic, unfortunately.
Rojo might be just through the door here but he has played football before. He is a typical World Cup signing. He may continue to show the form that got Argentins to the final, he may not. I don't think his performances at Sporting put him in the top tier of promising defenders in Europe.
I don't think he offers anything more than what we have in Smalling, Evans, Jones and Shaw - except that those four are British and therefore more likely to stay, and can count towards our homegrown count.
In the scenario we were in this summer, there is no doubt we should have bought an experienced, older, reliable CB rather than another young prospect, when looking at the players we already had. I don't see how that is open for debate.
