For now, the Premier League teams are still favored and taken into account in the UCL stage, but Aston Villa's victory over Bayern was quite surprising in my opinion because no one expected that Aston Villa would be able to win the match and for Manchester City, Liverpool and Arsenal I think they won the match fairly because since before the PL team was very favored, even for this season Manchester City is still the top favorite to win the Champion League.
it was a really commendable one from Aston Villa in that game, even when it felt like they were lucky, it still turned out they are winners and have been able to get the complete points in that game unlike before when they will be struggling at some point to win Bayern Munich in a champions league game where they aren't experienced enough, even in the game it was obvious they were not playing really well but were just defensive and got lucky at some point with which they were able to secure the victory. all premier league teams are doing well.
It is obvious that Aston Villa and other English teams are doing quite well in the new format of the Champions League this season. The historic victory of Aston Villa over Bayern Munich was actually not expected by football speculators. This led to gamblers losing a lot of money because no one actually did believe that Bayern Munich will go 90 minutes in the pitch without scoring a goal against Aston Villa.
Also Aston Villa had also extended such level of performance to English Premier League, where they are occupying a pretty nice position in the table. I am however doubtful that Aston Villa would continue this excellent performance both in local League and in Champions League. Maybe Manchester United this weekend is a test for them, if Aston Villa eventually outsmart Manchester United, I'll give them all their flowers.
