It's almost like PSG found a formula for beating English clubs. First Liverpool, then Aston Villa, now they are halfway through of eliminating Arsenal.
It was an even game, but I think it's fair to say that PSG deserved the win, as they created more and better chances. Arsenal looked decent, they even scored an equaliser but it got denied due to offside. It just wasn't enough, though.
Looking at Home/Away stats for both teams in their respective leagues, it seems like both of them are performing almost equally at home as they do in away games. This means the home advantage for PSG might not be as big of a factor as some would expect, and this is still anyone's game.
