Olympiakos clinched the Greek league title on Sunday following a 3-0 win over AEK Athens.
The win left Olympiakos 16 points clear of nearest rivals Asteras Tripolis with only five matches remaining of a campaign in which they have only once tasted defeat.
Greek international Avraam Papadopoulos scored in either half and Algerian Djamel Abdoun scored the other goal as Olympiakos romped to victory on what was the club's 88th birthday.
The title was achieved despite the mid-season sacking of Portuguese coach Leonardo Jardim, who was dismissed after the team's elimination from the Champions League. Antonios Nikopolidis took his place.
The Greek season has also been marked by the country's financial crisis which has affected several clubs, including 20-times champions Panathinaikos who are only fifth this term.
