Fiorentina midfielder Borja Valero has admitted that being without injured striker Giuseppe Rossi will be a big blow for the Serie A side.

Rossi, who suffered an ankle injury in the 1-0 win against Livorno, is expected to miss up to seven weeks despite initial fears that he had damaged his anterior cruciate ligament.

"It's always difficult to do without a player of Giuseppe's level and we will miss him a lot," Goal.com quotes Valero as saying.

"Fortunately we have other champions in the squad and they proved that against Chievo. It's positive that we have different options and can take on so many different tactical systems."

Viola are pushing for a Champions League qualifying spot this season and currently sit fourth.
