ATHENS, Greece (AP) — Olympiakos was held to a 0-0 draw by host PAOK in the Greek league Sunday after three key first-half saves by goalkeeper Charles Itandje denied the league leader a win.

The draw allowed Panathinaikos to take sole possession of second place with a 1-0 win over visiting Panetolikos to sit six points behind defending champion Olympiakos. PAOK remained eight points behind Olympiakos.

PAOK fans clashed with police before the game and seven people were arrested, but it was peaceful inside the stadium.

Also, Platanias beat Panthrakikos 2-0 and Kerkyra drew 0-0 at Panionios.
