Defending champion Olympiakos beat host Xanthi 2-0 in a clash between the top two Greek league teams on Sunday.
Brown Ideye opened the scoring in the 38th minute with a volley from inside the area and Luka Milivojevic made it 2-0 with a free kick in the 88th.
Both teams ended the game with 10 players. Xanthi’s Christos Lisgaras was sent off around the hour mark with a direct red card for a violent tackle on Seba, who was also dismissed for going after his opponent when he got up.
The win gave Olympiakos a 12-point lead over Panionios — which beat Panetolikos 2-0 — and Xanthi.
Also Sunday, Giannena upset host PAOK 1-0 and Platanias beat Larissa 3-2.
