Tirri's ties are predominately based in Milan and the original directors of the Galactico's era at Madrid, I suppose it's not out of the question he could somehow manufacture Tevez a move to Real Madrid. The question then becomes, how much faith does Jose Mourinho have in Benzema/Higuain? Zidane, director at Madrid now, has so much faith in Benzema that he even let Karim stay at his house to settle in. A few stumbles on that move for sure.
As for the move to Juventus, I highly doubt that will happen. Beppe's just re capped the wage structure at Juve from £110k a week to £95k a week, Tevez would annihilate that. The days of mega signings for Juve have gone, and being frank we really don't need another striker especially considering the investment in Matri. Apart from him being involved in acquiring Gabriel his ties to Turin are pretty meaningless...
Tirri is also the same guy who took a bung of £10 million to smooth over the Walter Samuel transfer to Inter Milan, he's hardly an angel which means it does not surprise me one bit he's siding with Kia and MSI who I know are still behind Carlos somewhere despite the original MSI company folding.
To put down the Juve rumor: Juve expect to generate £40m in pure profit's this season with the new stadium, when you factor in Conte and Beppe's vision of building a squad it's hard to see them buying Tevez on £11 million a year.
Bit of difficulty in the Anzhi move, one of the old 3 billionaire's that used to own a stake in Tevez is actually an exiled Russian billionaire who is one of Putin's fiercest rivals. Putin's backing is key to Anzhi, his idea is getting his billionaire's to give back to Russia's regions and Anzhi is the benchmark at the moment. You look at the fact that a Putin 'backed' (Although never proven) businessman tried to buy out Tevez 3 years ago when his future at United was unclear, and Kia Joorabchian essentially fobbed them off. It;s going to be difficult to say the least to broker that deal, he has a 10 million pound mansion in a Cheshire village with a fair few million in the bank I'm sure. If he really wanted to leave for the reasons he said, he would have taken the 75% paycut by now and gone off to live out his career in Argentina.
Problem is, Kia wouldn't be happy taking his cash cow away. That's the main bit I don't understand, he's not going to get any more money elsewhere in world football. Bank up the money for a year and cash in on the transfer next summer, that way Kia gets his money and Tevez gets his retirement.
