Real Madrid are the toughest team Arsenal could face in the quarter-final, with Atletico Madrid, Bayern Munich and Bayer Leverkusen other potential opponents at that stage.
ARSENAL could face a nightmare path to the Champions League final after Real Madrid beat Manchester City.
If Arsenal progress past one of those teams they could come up against Premier League title rivals Liverpool.
Both those sides were picked out of the hat on the same side of the draw as Arsenal, so the Gunners could meet Real in the quarter-final.
By contrast Liverpool have an easier set of fixtures up until the semi-final, with PSG and Borussia Dortmund arguably the most difficult teams they could potentially face.
