Sporting director Pantaleo Corvino has revealed that Fiorentina have turned down offers for Riccardo Montolivo, Alberto Gilardino and Juan Vargas.
Midfielder Montolivo was linked with a move to Arsenal earlier in the summer, although his agent denied that talks had taken place.
The futures of defender Vargas and striker Gilardino have also been the subject of speculation after impressive campaigns in 2009/10.
All three players have now attracted firm interest, but Corvino insists they will not be going anywhere.
"We have received offers for Montolivo, Gilardino and Vargas, but this group of players is untouchable," he told Sportmediaset.
