PAOK bests Olympiakos 2-1 at Karaiskakis Stadium

Pareyra grabbed the winner shortly after the break, netting from distance. PAOK held on thanks to a handful of fine saves from Glykos, while a late shot from Alejandro Dominguez hit the crossbar.

"We weren't afraid and the win came," Athanasiadis said. "We knew they'd press us and that we'd find space on the counterattacks. To come here, win, and stay top, that's a big psychological boost for us."

Season surprise Kalloni stayed third despite losing 2-1 at Xanthi, while PAS Giannena suffered a humiliating 4-0 loss at home to Levadiakos. Veria held Atromitos 0-0, and Kerkyra and Panthrakikos both won 1-0 at home, beating Panionios and Platanias.

Panathinaikos are hoping to move up to third place when they travel to Panaitolikos Thursday. Niki Volos takes on Asteras, while OFI faces Ergotelis in a Cretan derby.

The midweek games were added after the Greek Superleague was twice suspended this season due to violence.
