Juventus won their last 2 home games against Napoli and Verona in the league.
On the other hand, Spal only won 1 of their last 5 league games as the 2nd bottom team in the league.
These two teams are not at the same level at all, and the AH line is home team (-1.50) with short odds.
Therefore Juventus are likely to take an easy win.
