The results are not that surprising for big teams like Manchester City and Barcelona who won easily against weak teams in their groups. However, several other results were no less exciting, such as PSG vs Dortmund which was finally won by the host PSG with a score of 2-0 and also Porto who managed to beat the host Galatasaray with a score of 1-3. For Leipzig, from the start, I had no doubts at all about the performance of this German team because basically their current attack line is also one of the strongest and they managed to beat hosts Young Boys with a score of 1-3.
However, there was one match that was quite boring with no goals being scored, namely Milan vs Newcastle and even though I know there were a lot of saves made by the Newcastle goalkeeper, Newcastle in this match still seemed to only be aiming for a draw rather than counterattacking.

Porto and Leipzig were the visiting teams who successfully beat their opponents but that was because their opponents were not as strong as them. Atletico Madrid almost got good results like Porto and Leipzig but Lazio's enthusiasm and their goalkeeper managed to score a goal in the final minutes of the match which was extraordinary because it saved Lazio from defeat at home game.
Newcastle realized that playing more openly would make their defense easier for AC Milan to penetrate, but in fact, Newcastle did not apply a defensive strategy because they placed 3 attackers in front, only that it was difficult for them to counterattack because AC Milan played very pressingly and quite dominated the match. When they played at home, Newcastle opened up the opportunity to win so they are a team that other teams in the group have to take into account.
