There is big difference between these two teams. Pontedera is now on 7th place, they are fighting for top of league. Today they play against the weak team in the league so I expect they are able to score more goals than ususal. In last 5 games they played 3 times with over 2.5 goals.
Forli is now on 15th place. They play with averagley 2.64 goals per game. In last 5 games they played 3 times with over 2.5 goals.
My pick: over 2.5 goals.
