 With Guidolin back at the helm of Palermo in 2006–07, Biava regained a more important role in the Palermo squad, returning to play at his usual levels.During the summer 2007, Biava refused an offer from his childhood team Atalanta, preferring instead to stay at Palermo even though the club management could not ensure him a place as a regular.He successively agreed a contract extension with the "rosanero" until June 2009.
