Because abramovich is doing that for his own interest not the club's.He is a criminal(100% post-KGB guy and a war profiter).We don't need those kind of owners an I don't want to have babuska instead of Juve's sign.We are Italian club and we need to stay that.Abramovich is the owner of CSKA and who knows what he owns at the same time.I don't want that in Juve.Sorry Lion,but abramovich is (most probable) Putin's main guy who is spreading russian influence in the West.
Actually I was shocked last year while Chelsea fans were singing russian kakalin(song) after the game against Liverpool.That's a shame,a shame for England and Eng football.
And one more thing:he bought Smertin from CSKA Moscow and than transfered him to some other club,that is the money circulation.
