BBC Sport's Alex Howell assesses why Arsenal fans should still be hopeful that their side can reach the Champions League final.

Arsenal have already accumulated 67 points so would require another six points (73) to be absolutely certain of Champions League qualification. That works out to be two wins. Five points - one win and two draws - should also be enough given their superior goal difference.

Paris Saint-Germain must go to Strasbourg this weekend, in between the two legs of their Champions League semi-final against Arsenal, for a clash with one of a host of sides scrapping to qualify from Ligue 1 for Europe's elite club competition next season.
