Olympiakos has confirmed its second consecutive title in the Super League, and 46th overall in the Greek top flight, after beating Panathinaikos on Sunday. At the same time, Aris suffered a home reverse to AEK.
Olympiakos came from behind to beat Panathinaikos 3-1 on Sunday and create a safe lead of 22 points at the top of the table, with seven games left to play.
Panathinaikos took the lead with a Federico Macheda penalty just after the half-hour point, but substitute Ahmed Hassan equalized in the first-half injury time.
It was only after Panathinaikos was left with ten men, through the second yellow card shown to Achilleas Pougouras, that Olympiakos managed to get ahead with Hassan again before Bruma closed the game out with the last kick of the game.
