Milan deserved the win by every metric. They had a whopping seven big chances, 20 total shots and six shots on targets, which led to an Expected Goals number of 3.51. However, Allegri will be annoyed that Cremonese had spells on top in the game, with 15 shots and three on target, plus six corners for the hosts and 0.99 xG.
I haven't seen many players so far who play more than two or three years at full capacity and have scored more than 40 goals. That's why I think that in general the level of goals has dropped a little, as was seen last season.
