I have the saddest news for Arsenal and their fans, if they really lose to PSG in Leg 2, what's so special about Arsenal? Still without a trophy every season, and in the EPL only runner up and also not special because positions 3, 4 and 5 all have UCL tickets.
0-1 difference over PSG still has a chance but it will happen at the opponent's home and I think PSG will be much more careful to keep maximizing the opportunity. Barcelona finally got a worthy opponent, Inter was underestimated but when we see the results of Leg 1 we will be quite sure Inter have a chance to give Barcelona a nightmare.
If Arsenal lose to PSG in the second leg it will be disastrous as they will record another season without a trophy in a row. The one goal difference isn’t much, Arsenal have a good chance in the second leg to make history but seeing how poor they have been performing lately in the Premier League I fear they might concede more goals against PSG in the second leg.
