i 100% agree with you on the vidal or Schweinsteiger... unrealistic targets point
but equally i don't think buying rejects from other clubs is away to rebuild our squad. I also Don't think signing players for signings sake is a good idea.
we have 5 current Center midfielders in our squad, arguably all of whom should be nothing more than a squad player at a top side(in anndersons case should be anywhere near a top side), i do not want us to compound that problem by adding another player in the same mould.
ill admit that if song re-found his form he showed in his last season at arsenal then he would be a slight upgrade on what we have, but what if he carryes on playing like he did in the world cup, which even without the red card was poor, or his form at barca, or his form at arsenal before his last season which was inconsistent at best.
i think buying a player who has had far more poor/inconsistent seasons than good seasons as a player is a stupid gamble. espically when the upside isn't enough t make it worth while.
i honestly would rather us sign no one then bring in players like song and vermarlen, as we currently have far to many inconsistent squad players on wages so high they almost impossible too sell, and gambling on bring more players in who fit that description is a sure fire way to make the situation worse rather then better.
as at least that way we have some flexbility in the squad and we arnt just pi$$ing money down the drain
