Motivation might give Milan an extra boost, but I would still be more cautious about betting on a Milan win. Lecce shouldn't be underestimated, and based on their previous match, they managed to draw against Genoa away from home. Genoa had always beaten Lecce in their last 5 encounters. Meanwhile, Milan recently played at home but were defeated by a newly promoted serie A team. So in my opinion, betting on a Milan win is a bit more risky, and I would prefer to bet on BTTS (Yes)
On paper, the imbalance in the teams' strengths is too great. Plus, for Milan, this is an away game, so the odds are still a little higher than they could be. I took the risk, 1.58 seemed to me to be a normal compensation for the risk. I can't say there's a lot of value here, but having scored zero points in the first round, Milan is obliged to beat the second outsider. If it were the end of the season when the teams' prospects were already determined (Milan is out of the title race and let's say their place in the top 4 is secure or, on the contrary, there is no chance anymore) then I would not place a bet.
