Djibril Cisse celebrated his return to the French national soccer team with a couple of goals that kept Panathinaikos at the head of the table, as all top six teams in the Super League scored victories over the weekend. The Greens stayed two points ahead of Olympiakos and PAOK thanks to their 2-0 victory at Panionios with one goal in each half last night. Cisse took his tally to 20 goals in the league this season, scoring at the 21st minute from the penalty spot and at the 55th through an excellent personal effort and a right-foot shot which the Panionios keeper could not stop. Olympiakos beat visiting Atromitos by the same score, courtesy of goals by former Blackburn Rovers striker Matt Derbyshire and Greece international Costas Mitroglou, the latter in injury time with the Atromitos goalkeeper having gone to the Olympiakos box in a desperate effort for the equalizing goal. PAOK breezed past Xanthi with a 3-0 away victory in Thrace on Saturday with Vieirinha scoring a brace and Vladan Ivic adding the third. AEK, in fourth, had to sweat before beating Ergotelis 1-0 at home, with Rafik Djebbour to thank for its goal. Aris beat 10-man Larissa 2-0 at home to stay two points ahead of Kavala, which defeated last-placed Panthrakikos 3-1 away. Iraklis bounced back from previously disappointing performances with an emphatic 4-0 win at Asteras Tripolis but it was Levadiakos that scored the most important win of the weekend, beating fellow struggler PAS Yiannina 4-1 at home and dragging Larissa down to the relegation zone. Panathinaikos leads with 55 points from 24 games, ahead of Olympiakos and PAOK with 53, AEK with 42, Aris with 38 and Kavala with 36. At the bottom of the table, Panthrakikos has 12, PAS Yiannina has 21, while Levadiakos and Larissa share the third spot that leads to the second division, with 24 points.
