Let's see if things will work out as you said; if not, Arsenal winning against PSG at home is going to be a difficult thing to happen, although it's football, and I’m also hoping to see that happen. Just that I’m curious because we already saw what happened at Arsenal's home when PSG came; they failed to utilise the advantage of being at home to win against PSG.
Arsenal didn’t win the match against PSG in their own home but that doesn’t mean that they can’t win in the coming second leg match which is very crucial for them to book a spot in the champions league finals this season. They may have eliminated Real Madrid from the champions league but that doesn’t guarantee them success in the remaining games if they don’t put the best effort in this games and prevail as it should be. PSG are a fierce team and they’re also looking to win their champions league trophy for the first time also, so it’s going to be a tough challenge for both teams before they can advance to the finals. A one goal difference is not too much to be equaliser, so I foresee a tough game in this match.
Inter Milan and PSG have bad news of injuries of main attacking players, Lautaro Martinez and Dembele. It's advantage for Barcelona and Arsenal and if they are two clubs participate in a final match, they will repeat their final match against each other many years ago, in
2005 - 2006 season.If this players are yet to be ruled out of the games, there is still a high chance that they may still play in the finals if their injuries are being boosted to recover rapidly, they are both main players in each of their respective teams. Having said that, I still feel a tough challenge will be seen from both games and no team can boast of qualifying to the final at this stage now. A repetition could happen as you’ve said, but no assurance of it happening at all until we see what each team has to show in the finals.
