In fact, I hope Liverpool will continue to appear with their main players, apart from the match against Milan there will be no effect at all because Liverpool's 15 points cannot be pursued by other teams. If Liverpool beat Milan the match between Porto versus Atletico Madrid is a game that is quite important like a final, whoever wins will qualify for the next round.
This will be difficult because their performance is very much different, Especially if we look at AC Milan's last 5 matches in all competitions, They can only win the match against athletico and after that nothing else. In contrast to the Liverpool match which is so overpowered.
I myself really doubt they beat Liverpool in this match.
Basically Liverpool must prioritize the EPL for now, because in the UCL Liverpool have definitely qualified. If later against Milan, Liverpool is still targeting 3 points, then obviously Liverpool prefers to prioritize their prestige in the UCL which I don't think is important for now. Because after all, after Milan was able to win away yesterday against Atlético, at least Milan again has hope of being able to qualify and so also in the last match against Liverpool of course Milan will fight hard to win at the San Siro.
