On the contrary, I think FIF suffers from greatly underestimating Milan sometimes. Maldini has done remarkably well for a rookie DS, he has a clear plan & strong convictions. These are not excuses, its an opinion.
You are criticising Milan for missing out on Botman, when they already have Kjaer as a back up CB, followed by Gabbia. Inter play with 3 CB's and our first back up is D'Ambrosio, followed by Dimarco - both fullbacks. De Vrij doesn't even have a back up. Its not even the same level of a problem. So its only fair that Inter get more critique on this one than Milan.
