Olympiakos leaves it late, Greens win at Aris

Olympiakos scraped past a rigid PAS Giannina defense with a late winner on Sunday, but the weekend's triumph belonged to Panathinaikos that beat Aris away and is back in the mix for a European spot.

The Reds needed an injury-time strike by substitute Ahmed Hassan to beat PAS 1-0 in Piraeus and climb to 45 points from 17 games. They missed numerous chances to score earlier, including a Mathieu Valbuena penalty that keeper Lefteris Houtesiotis saved.

AEK stayed nine points off the pace thanks to a 2-1 win at home over Atromitos, goals coming from a Nelson Oliveira penalty and Marko Livaja header. Lazaros Christodoulopoulos pulled one back for Atromitos, also from the spot.

Third-placed PAOK rose to 35 points through an easy 3-0 win at 10-man OFI, courtesy of goals by Christos Tzolis, Fernando Varela and Michael Krmencik.
