Fiorentina have signed talented Cagliari midfielder Massimo Gobbi, after completing two deals with Treviso.
Gobbi has moved to the Stadio Artemi Franchi after two goals in 33 starts in an impressive Serie A season.
Midfielder Gianni Guigou, 31, meanwhile has completed a permanent switch to Treviso following his loan move to the Stadio Ombono Tenni in January.
Twenty-two-year-old Brazilian striker Ferreira Reginaldo has gone the other way, as Viola have taken joint ownership in the hit-man.
He was top scorer at Treviso last season, along with Milan loanee Marco Borriello, but will now join up with Cesare Prandelli's side.
The news will come as a welcome boost for Viola fans, but at the same time increase speculation that the club may yet yield to advances on star man Luca Toni.
