This points to a major problem for Milan. Taking 24 shots and scoring only one goal is a clear indication that Milan's attacking strategy isn't strong enough. Cremonese, on the other hand, scored some magnificent goals, but there was nothing Milan or their goalkeeper could do about it. It was an unfortunate and poor match for Milan. They dropped points, a point they'll remember until the end of the season.
You forgot to mention the 6 shots on target which I think is the most important but Ac Milan could only get 1 out of the 6 on target in the goalpost, that doesn't show how serious they are to be even as of last season I never saw Ac Milan as one of the teams to compete for any domestic titles. The annoying part is, they have the players but getting the job done is a major problem and they shouldn't blame the coach because I don't know how they couldn't dominate the newly promoted side Cremonese. Milan was struggling to play as a unit in that encounter like their defense and the midfield wasn't strong enough to match Cremonese players and if they can't be at their best against Cremonese I don't see them getting anything against the big sides this season.
