Genoa coach Gian Piero Gasperini has hit out at fans for being "too negative".
Genoa currently sit in tenth position on the Serie A table.
"Here at Genoa, there is too much negativity, it's a different environment from that of years ago," Gasperini told reporters after Monday's 1-1 draw with Empoli.
"The fans have lived through difficult times, but this is a team that deserves to be supported and not only attacked.
"Some people don't deserve to support a team, because they're incompetent and ditch players of a good standard to promote others who haven't played."
He continued: "We are a team that are appreciated by most of our fans, but we have to raise our voice against a minority.
"I hope that anyone who loves Genoa has a better attitude, because anyone who wishes to destroy a team should not follow football.
"In recent years, Genoa became more famous for their jerseys being delivered to fans during matches.
"We're doing a lot to add value to this team. The President has worked through many obstacles. I think that even our most ardent fans deserve better."
