Fiorentina are looking to extend the contracts of three key players before the end of the season.
Spanish midfielder Borja Valero is at the top of the list and renewal talks are already at an advanced stage.
Currently contracted until 2016, he should get an improved deal which will now run to 2018.
Once those discussions have been concluded, the Viola are then set to turn their attention to Alberto Aquilani and Gonzalo Rodriguez.
The Italian international midfielder and the centre-back are presently both committed to the outfit until June 2015.
