A comprehensive 3-1 win over Kerkyra was enough for Olympiacos to start the celebrations after securing the Greek league title for the ninth time in ten years on Sunday.
Closest rivals AEK Athens guaranteed second spot with a 5-1 win over bottom club Ionikos as third-placed Panathinaikos slipped to a 1-0 defeat at home to Aris.
AEK could still finish with the same number of points as Olympiacos but the head-to-head record between the clubs favours the Piraeus club who beat AEK at home and drew away.
It is the third year in succession that Olympiacos have won the championship and the 35th time in their history.
Any nerves were settled in the second minute when Rivaldo, who was only cleared to play on Thursday when a disciplinary tribunal overturned last week′s red card, slipped in to put the champions one up.
The Brazilian was at the centre of a hotly disputed penalty - he appeared to dive as the Kerkyra goalkeeper came out - which Serbian Predrag Djordjevic duly converted to make it 2-0 at the break.
Nery Alberto Castillo clinched the game with a third goal shortly after the restart and although Kerkyra pulled one back, Olympiacos held on comfortably.
Pantelis Kafes put AEK ahead after 22 minutes only for Benjamin Onwuachi to equalise for Ionikos before halftime.
AEK, however, ran away with the game in the second half with Leonidas Kampadais, Nikos Liberopoulos twice and Pantelis Kapetanos scoring.
The best individual performance of the day came from Xanthi striker Stavros Lambriakos who scored all four in his side′s 4-1 win over OFI Crete.
At the bottom of the table, Iraklis grabbed a lifeline when they beat fellow strugglers Egaleo 1-0.

Greece coach Otto Rehhagel on Friday called up promising Olympiakos Piraeus defender Vassilis Torosidis for the European champions' friendly against South Korea at Fulham's Craven Cottage ground in London on Feb. 6.
Striker Angelos Haristeas, back in goal-scoring form after joining Feyernoord from Ajax Amsterdam last year, also returns to the team. He had missed his team's last international friendly against France in November due to an injury.
Torosidis has quickly won a starting spot with Olympiakos since joining the champions on Jan. 1 from Xanthi.
"This is a first step for me," said Torosidis, one of the country's most exciting young defenders. "Now I will have to prove that my call-up was worth it."
