Panathinaikos broke the deadlock in the 66th, when Vyntra headed in a corner taken by Sotiris Ninis. Cisse made it 2-0 in the 80th from a cross by Brazil midfielder Gilberto Silva to score his seventh goal of the season.

Panathinaikos has 28 points, two more than defending champion Olympiakos, which drew 1-1 at home with Iraklis on Saturday.

Also Sunday, it was: Asteras 3, Giannena 0; Atromitos 0, Ergotelis 0 and Xanthi 1, Panionios 2.

Seeking a win in order to take advantage of Olympiakos' draw, Panathinaikos attacked from the kickoff and squandered a major chance when a shot by Cisse in the fifth minute hit the post.

The France striker, who moved to Panathinaikos this season from Marseilles, had another scoring opportunity in the 22nd when he shot wide from the six-meter (yard) area.

Levadiakos, struggling to avoid relegation, defended stoutly but failed to create much in attack. The hosts' best chance came in the 74th, when a blistering shot by Stefano Napoleoni forced goalkeeper Alexandros Tzorvas to palm the ball over the crossbar.

AEK Athens hosts Larissa on Monday.
