Either way, one of them will lose. The second leg decider will be a hard work for both teams to show a fierce competition. Arsenal had some problems in the first leg, maybe they also got pressure when they had to play well and win the match, unfortunately the result was not as expected. PSG played well, and the second leg will be quite difficult for Arsenal too. But they still have a chance if they make a miracle that surprises PSG.
I hope that miracle comes when they needed it the most because the Gunners have come along way for this very campaign and also PSG too but I'd prefer the Gunners to make it to the finals, how many years now that they haven't seen a champions league final, it will be disturbing honestly. But that lack of consistency is the major problem Arsenal are having at the moment, you'd see them getting a perfect display and the next game you begin to wonder if this was the team that made the game of football look easy? Now you feel what I'm saying, last time Madrid was the barrier and they didn't think twice before knocking the Spanish team out and we thought that the momentum would still be their, in their next game they messed up now the same silly mistake wants to repeat itself, to tell you the truth I feel tired and sad for a club that plays good football but could not stay that good for long.
However PSG is also a team that really wants the Champions League trophy. They are currently performing more convincingly than in the qualifying round. Especially now they are ahead, and of course their spirit will continue to increase.
I also actually prefer Arsenal for the final match. But who knows what will happen in the second leg. A surprise could happen, or conversely Arsenal might get even worse.
And you know that PSG are some how like Arsenal, very disappointing when you expect an outstanding performance like they can get to the finals and you'd see them playing like a low division team that mistakenly got into the finals and is some how good to see both teams that's PSG and Arsenal playing the semis against each other, at least it will give them that high spirit of fighting much better if any of them get to the finals. As it stands for the Gunners they don't have to give us any excuse to as why they'll lose or crash out of the champions league this period, no FA Cup games, no Carabao Cup games and they are not fighting for the EPL title any more so they need to channel all their efforts to the second leg and I don't even expect them to win the game against Bournemouth this weekend.
