Arsenal can book their place in the last 16 of the Champions League on their return to Europe's elite club competition after a seven-year absence if they avoid defeat to Lens at the Emirates Stadium.
The Gunners lead the group with nine points, four clear of second-placed PSV. For their part, the Ligue 1 side sit third, level on five points with the Dutch side, so a shock win against Mikel Arteta's side would put them in a favourable position to qualify for the last 16.
The Premier League side's coach Mikel Arteta spoke at a press conference ahead of the key match against the French side, making it clear that his team's priority is to qualify as group winners. Check out what the Spaniard had to say.
