Florence, January 4 - Injured Italy forward Giuseppe Rossi is has joined Fiorentina from Spanish side Villarreal in a nine-million-euro deal, the Florence club announced Friday. The inventive 25-year-old was a regular Azzurri starter before suffering a nasty knee-ligament injury playing for Villarreal against Real Madrid in October 2011. He has not played since as he also suffered another injury to the same knee last year before he was able to return. He is expected to resume action in March. The Fiorentina side have agreed to pay just over two million euros annually in a four-year contract plus bonuses.
