Olympiacos stretched their advantage at the top of the Super League to seven points with a 3-1 win over Levadiakos. The league leaders were 2-0 up by half-time thanks to a 41st-minute own goal from Panagiotis Korbos and Kevin Mirallas\' strike three minutes later. Stefano Napoleoni pulled one back after 65 minutes but Mirallas bagged his second two minutes later to finish the game off. AEK Athens lost ground on the leaders as they were held to a 1-1 home draw by FC Xanthi. Marko Markovski put the visitors ahead in the 29th minute but Leonardo\'s penalty on the stroke of half-time ensured the spoils were shared. Panathinaikos, level on points with AEK but with three games in hand on them and Olympiacos, face Giannina tomorrow. In the day\'s other game, basement boys Doxa Dramas, with only one goal and three points to their name in 11 games, lost 2-0 at OFI Crete. Fotis Papoulis sealed the points with a second-half double.
