AEK moved to second in the Greek league with a 2-0 away victory over newcomer Levadiakos on Saturday.
Dimitris Sialmas scored once in each half and got sent off. He was booked after his first goal for excessive celebration, and received another yellow card in the 82nd minute for a dangerous challenge.
AEK was four points behind Olympiakos and two ahead of Panathinaikos, which has played three fewer games. Olympiakos travels to last-place Drama and Panathinaikos hosts Kerkyra on Sunday.
Also, Asteras beat Panaitolikos 1-0 and Ergotelis defeated Panionios with the same score.
