Arsenal will be without Martin Zubimendi and Piero Hincapie for Tuesday's Champions League meeting with Lille after both players suffered ankle injuries during a post-match training session following the victory over Leeds United.
Arsenal have completed the permanent signing of defender Piero Hincapie after the Ecuador international spent last season on loan from Bundesliga club Bayer Leverkusen.
Piero Hincapie has said Arsenal are ready for a "very difficult game" as they prepare to face Manchester City in Sunday's Carabao Cup final at Wembley Stadium.
