Athens-Sana
Greek champions Olympiakos drew 2-2 at home to Champions League runners-up Tottenham Hotspur last season at the start of their Group B campaign.
Tottenham scored the first goal with a penalty from Harry Kane and Lucas doubled the lead but Daniel Bodense pulled one back for the break and Olympiacos equalized in the 54th minute with a penalty from Matteo Valbuena's keeper Hugo Lloris.
Tottenham were the most dangerous side in the final stages, but Dili Alli and Eric Lamela squandered the chances.
