After overtaking PSV to take the lead in the Premier League over the weekend, Arsenal will be looking to build on that momentum as they host Lens in a match that could see the north London team grow to the Champions League knockout stages. With nine points at the top of UCL Group B, four points ahead of their nearest rivals, PSV, the Gunners have only lost once in the competition, which came against their opponents tonight in the rematch in France. That previous encounter demonstrated Lens’s counter-attacking prowess, but the French team, who are level on points with PSV, are terrible on the road, having failed to win 13 of their previous away games in the UEFA Club Competition.
