Thanks for posting these articles. Here's my take on them for what it is worth:
1. Ramos - He is complaining that he wanted to sign Eto and Villa and instead got Pavluchenko and Bent instead. The same Villa who that summer refused to go anywhere including Real Madrid meaning that Schuster accused him of lacking ambition! The same Eto who was at Barcelona at the time! If Pochettino had a go at Levy for not signing Messi, Ronaldo, Neymar, Iniesta or Suarez I think we'd all agree that was unfair!
2. Harry Redknapp - He is complaining that we signed Saha and Nelson instead of Tevez and Cahill. He says in the same article, Tevez wanted £200k a week which we obviously could not afford. And Cahill went to Chel53a. How could we compete with them?
3. AVB - Now this is the interesting one. He wanted Moutinho, Willian, Oscar and Damiao. Willian and Oscar we could do nothing about, they went for bigger wages and Champions League elsewhere. Moutinho was third party ownership issues and then went for stupid money and wages to one of the richest clubs in the world. Damiao - well it seems like no one can sign him! In that same article he complains about losing VdV, who just recently slated AVB because he didn't feel wanted by him. He also says Baldini was imminently going to leave. Hasn't happened.
Who really knows what the truth is? You are choosing to believe these three which is fair enough. I don't as Ramos and Redknapp were asking for the outrageous and I wouldn't trust AVB as far as I could throw Hulk.
