Milan had domination during the match, not only in ball possession but also in other cases. During the match, Milan was so calmly attacking. Well, they may not be too offensive in the first half. But it is quite different in the second half where Milan did more attacks and possession. That is why Rennes seems not having nay chance to get closer into Milan defense. This is a good start for Milan, so that they really can join the next qualification. Because I am also sure enough that in the second leg, Milan will be also leading.
AC Milan vs Rennes can be considered an already completed tie in my opinion, because there is no way this Rennes team would over such deficit against Milan, the most they can even get at their home in the 2nd leg would be a draw.

Is anyone else following how awful Ajax have become the season, they turned what should have been easy for them into a 2 goal deficit, fortunately enough for them they were able to recover during the additional minutes of the second half, first from the penalty spot, with Bodo/Glimt down to 10 men, and restored parity in the 96th minute of the game. Ajax would be playing the second leg away from home, and even though I'd be expecting them to win and advance to the next round, but I strongly doubt they can go far in the tournament when they face a better team and a real test.
