Arsenal are more dominant than PSG. It's pretty obvious that Arsenal will be easily manage to grab the opportunity to jump into the final. Arsenal is playing a team play despite PSG only being reluctant on a few players. If Arsenal defense did its job to mark down their top player then apparently they can win the match. Because besides defensive tactics their attacking gears are also strong.
In the addition if we talked about Barcelona vs Inter Milan. My prediction will be that it goes for Barca because they are much more dominant than inter. This season they play so good. So I think Barcelona and Arsenal will be there to play the final of UEFA champions league. If this really happened, then obviously this match will be one of the most extraordinary and optimistic because both will be in an intense wish to win the final. But anyway, let's see what happens next....
