This part is so true. This will also have a big role in their quite likely elimination by Real Madrid in the Champions League. Arsenal are a loser in the PL in the first place. They are always watching some other teams lifting the PL trophy. 

Real Madrid have that winner mentality in this tournament. You have all seen how they still moved Atletico out of their way despite not playing good enough. I see Arsenal as a smaller hitch for them.

But after this stage the next opponent is most probably PSG. That's the point where things will get more interesting...
