Cesena is now on 19th place. This season they have goals difference 9-19 in 12 rounds played, it is averagely 2.33 goals per game. It is very low average.
Genoa is now on 5th place. I think it will be very dificult for Genoa to score goal. This season genoa play with averagely 2.33 goals per game.
As you can see both teams play with very little goals per game, so I bet on under 2.5 goals.
