For me, the Champions League is different, meaning that we think that a small team can beat the team above it because the game in the UCL is really tight, it can turn around, including Chelsea who are still not capable, even though what we see is that they can qualify in this group phase.
However Chelsea still have a wide chance of qualifying, as long as the upcoming match wins and wins so on, that's just Graham Potter how to do it.
Chelsea can lead first standing position awhile in Group E if success win from Milan and another games between Salzburg vs Dynamo Zagreb have draw. If next match win from Milan will easy for Chelsea keep lead to next round but will difficult choose keep failure take 3 points full on third games in Champion League.
