Yes, even though in the second half, Inter Milan dominated the match, they gave a very pressing attack to AC Milan. Only, some of their on-target kicks went astray and could be blocked by Milan's defense. I thought Inter would be much easier for that, but it turned out, even AC Milan was leading first in the first half.
I don't know why Inter always struggles when derby. They are not a problem when they meet another team, but stuck when they meet Milan. as well as AC Milan, They lost when meet Lazio, Torino and Bologna where not much good, but they are very excited to hold Inter Milan, and surprise us with the result. I also expect Inter will add a goal after balance it because they are dominate the match. Conceicao seem implement defensive strategy to hold the draw, while inter want finish with winning. I thing, Inter will advance to the next round basic what they did before. they should focus on winger to maximize ball supply.
The moment the word derby is attached to the match, the expected some funny outcomes because they are usually matches of two teams that are from.the same neighbourhood who understand one another better. That should be the reason it appeared like Inter Milan was not in their best form. Maybe the return match will be a lot different as it can be more competitive and will hardly end in a draw. The I can comfortably bet on Inter Milan to win because they are better positioned to win that match.
