This wont happen, at all, plus 40m is bogus.
But Moratti talks it up like he is trying a trade like that. And guess what? I welcome it, Eto'o scores alot, but so did Zlatan last year, plus he IS Inters whoooooooole creative force, without him they have been nothing but Maicon crosses. And Eto'o has regressed a little as individual player, now he is more wait for service and score then fuck whole defences up on his own. And Inter without Zlatan is rather robust and dont offer much service, even if Eto'o would score quite a bit with what he gets. He is more or less best scorer around. But Inter would lose aloooooooot in selling Ibra.
Only way they can recoup it is if they bough Cassano too, doubt it. Hleb has very little impact has a player, despite having the skill needed to create, he just has quite little end product and impact.
P.S I repeat, this wont happen, even if it could be a solution for both clubs in getting rid of two unhappy players while getting a top replacement.
