If there is only to be one "big money" signing this Summer, I would prefer Tevez.
Even if Babel is offloaded for decent money (we will struggle to get 7-8 million for him considering his regression), I could not see us affording both Tevez and Silva.
Silva is technically excellent, and would offer creativity and that "X factor" to turn the games that Torres and / or Gerrard are off form / stifled / injured.
BUT he is unproven in the rough and bustle of the Premiership - would he be able to handle it ; reminds me in a lot of ways of Garcia with his physical build and the way he plays.
Tevez on the other hand, has proven his worth here - he would be excellent ; has the whole package ; skill, guile, work rate, creativity, and strength ; effectively like Yossi and Dirk rolled into one.
He would be an excellent signing, and would become an absolute idol on the Kop if he came out stating that he wanted to leave the scum to join us.
Added bonus being the fact that Ferguson would be powerless to stop it happening ; I remember how smug he was on the Heinze affair ; would love to see his face if Tevez joined us.
Sign up Tevez ; give him the number 10 jersey ; he could operate in either the Torres or Gerrard role ; when they are all fit Rafa can decide who to play ; you can never have too many world class players ; the old addage in the 70's / 80's when we were so successful was to strengthen when we were on top ; we are so close now as it is, but sign a player of Tevez' calibre, and I think we will win the league next season.
I am not so sure about Silva though - by all means sign him if there are still adequate funds after Tevez, but I doubt that we will be that flush!
