]One thing that makes me feel confident for Chelsea who are unlikely to lose in the away match against Milan is about their new coach, Graham Potter seems to have a good ability because so far Chelsea have not lost after changing coaches. With a result like that it is very likely Chelsea will maintain this kind of performance at least not to lose points, a draw could be their target at the San Siro. I also don't think Milan are weak because so far Milan have had good results when playing at home, but when the Chelsea defense is at its best then the result is clean sheets for Chelsea because Chelsea have a good and strong defense.
I don't know whether it's Potter or not, but the team started to play well. Chelsea don't left Milan in the first match chances of winning, I don't know why something should change in the second match. Milan will play at home, it will be in favor of Milan, but I think Chelsea will still win, the only difference is that in this match, Milan will also be able to score a goal. Milan are playing well in Serie A, but they are weak in the Champions League, perhaps this is because the level of the Italian championship is not so high.
