Genoa are treating the Derby della Lanterna like a Scudetto decider, as Davide Ballardini has locked the team away to prepare.
The Grifone are already comfortably mid-table and have nothing to play for but pride, while Sampdoria are just one point clear of the relegation zone.
Coach Ballardini is keeping the levels of concentration as high as possible for the Sunday night kick-off.
He has decided not to speak to the media and locked the squad away by training behind closed doors today.
There are still fitness doubts over Marco Rossi, Emiliano Moretti and Rafinha.
