Liverpool is still unbeatable, they won in their last 6 CL matches, and Origi probably scored his first goal in the Champion League this season yesterday in their game against AC Milan. Milan performance so far in the Champion League have been poor, they were only able to win 1 match, while they lost 4. Winning the game against Liverpool could have given them the opportunity to play in the Europe League. Although, it seems their focus have been mainly on their Serie A matches. However, this is the end of the road for them in the Champion League.
In addition Liverpool broke another record for being the first EPL club to win all their group stage matchesin UCL, despite klopp making eight changes to his side by giving opportunity to other players, they convincingly won the match against AC milan, a good performance by Liverpool, next is the knock out stage which will be highly competitive though it obvious Liverpool will play a runner-up in another group being their group leader, I think their opponent wouldn't be formidable enough to beat them when the knock out stages kickoff in February 2022.
