Arsenal also had several chances to score but were always denied, but in this match PSG had more chances than Arsenal.
Do you believe that later in the second leg Arsenal will rise? I see PSG is much tougher at home.
My gut feeling tells me PSG is going to be the finalist, but who knows what Arteta will do on the second leg. Playing away at PSG is hard, especially if they can't control the midfield. On the other hand, Arsenal managed to defeat Madrid in the away game, so that's a good experience to hold on to. I guess it depends on how much the players want the UCL title, considering it's the only title Arsenal realistically can win while PSG is hunting for a treble. CMIIW.
Your gut feeling may be telling the truth. PSG started the game fast and scored an early goal, which disrupted Arsenal's game plan and they won the first leg with just that goal. PSG's pressure up front is disrupting Arteta's game. Arsenal tried to play with control under Mikel Arteta, but PSG's fast attacks and effectiveness in the midfield were a bit too much for Arsenal. I think the same scenario will happen in the second leg. I have the same gut feeling.
