If Arsenal were to beat one of the Madrid clubs, they would play either PSG, Liverpool, Club Brugge or Aston Villa in the semi-finals. Liverpool and PSG go head-to-head in the last-16 and the winner of that will be the strong favourite to reach the last-four and set up a potential clash with the Gunners.

Arsenal's Premier League title challenge looks shot and they are still hamstrung by injuries but Champions League glory is within reach, according to former great Thierry Henry.

There could be a rematch of the 2006 Champions League final if Arsenal can make it through, with Barcelona the current favourites to breeze through their side of the bracket and book a spot in the final.
