Genoa coach Cesare Prandelli says they must not freeze against Fiorentina.
The Grifone go head-to-head with the Viola, who could also still be relegated, but need to get a better result than Empoli manage away to Inter Milan to stay up.
Prandelli said, “It's marvellous to see and feeling the fans close gives us so much motivation. It's a game for everyone to get involved, as there is something crucial at stake and we can achieve it together.
“Fiorentina's style is all about changes of pace and through balls to break the offside trap, where they can be devastating, so we must stay solid at the back.
“When I arrived, I felt there would be a fight to the end and was proved right. We struggled to score goals over the last 10 rounds and that made it inevitable.
“There must be no fear. We are aware of the difficulties that we face, but cannot have room for fear. We just need focus and concentration."
