The only former winners left in the competition, Ajax will look to maintain a six-game winning streak at home in the UEFA Europa League as they host high-scoring Lyon.
• The sides have met four times in UEFA competition: two Ajax wins and two goalless draws.
• In 2011/12, they were paired in the UEFA Champions League group stage again, Rémi Garde's Lyon holding Frank de Boer's Ajax to two 0-0 draws. Current Ajax captain Davy Klaassen – then 18 – made his Ajax and UEFA club competition debut in the game in Lyon on 22 November 2011, and Alexandre Lacazette also made a cameo appearance.
• The teams for their last Amsterdam ArenA meeting on 14 September 2011:
Ajax: Vermeer, Van der Wiel, Alderweireld, Vertonghen, Sulejmani (Ebecilio 85), Eriksen, Sigthórsson (Bulykin 81), De Jong, Boilesen, Janssen (Anita 70), Boerrigter.
Lyon: Lloris, Koné, Lovren, Källström, Grenier, Bastos, Réveillère, Gomis (Belfodil 85), Briand, Cissokho, Gonalons* (Fofana 90).
