For the arsenal game, I actually enjoyed the first half more than the second half, because arsenal were literally sitting back, unlike the good performance they gave in the first half. PSG made two good substitute of Fabian ruiz and kolo Muani which actually changed the dynamic of the game, and gave more possession to PSG, but they couldn't break the arsenal's defense. Though PSG had two good chance that hit the cross bar, which was quite unlucky for them. I don't know how Enrique will be feeling right now for not taking dembele along. In as much as every manager deserves respect, I'm not sure if this decision would have solved anything.
And congrats to other teams that won their games. Leverkusen where able to crack the serie A code, after defeating Ac Milan. It's now 2 UCL losses for AC Milan, and this doesn't tell a good story about them. Six more games to go, maybe they can do something. As for city, it was business as usual. Barcelona had a good day at the office, and it's a good way to bounce back from a loss. As for Dortmund, they did great, and Adeyemi seems to be a good player. I used to know him as a LB, before changing to LW, and i watched him play RW in their game last week, but wasn't sure of what he played today. Congrats to all winners, and better luck to those who fought hard
For Arsenal, of course, they played very carefully because their target was to get 3 points and they managed to get it by beating PSG. I think some teams that lost in the second match of the Champions League must evaluate their performance to be better in the upcoming match. Because there is still a chance for them to improve their performance to be able to qualify for the next round.
