Fiorentina is determind to sign a defensive reinforcement for Paulo Sousa's squad. The Tuscan club's primary target is Vedran Corluka but the negotiation with Lokomotiv Moscow is quite difficult. Fiorentina has an agreement with the Croatian defender born in '86, but the Russian club has a new president who doesn't intend to let him leave. Lokomotiv is willing to not let Corluka play against Terek Grozny in an effort to make him fulfill the two years remaining on his contract. At the moment Fiorentina's pursuit of Corluka is complicated.
