Multiple reliable reports are claiming that Fiorentina are keeping tabs on Gabriele Zappa, who plies his trade as a defender for Cagliari. The move is still in the early stages, but interest appears to be growing. While Napoli have shown interest, Fiorentina currently lead the race - though the situation could evolve if a deal drags on. So far in this season, Fiorentina are conceding 1.57 goals a game (36 in 23), more than they'd like compared to the Serie A standard. The hope is Gabriele Zappa adds a bit of steel and helps make them tougher to break down. Speculation continues to connect Fiorentina with Auston Trusty, Soungoutou Magassa and Kyle Walker-Peters while no fresh rumours surround Cagliari. Looking for Fiorentina transfer rumours?
