Olympiakos Piraeus claimed their second successive Greek championship and their ninth title in 10 years on Sunday in spite of losing 2-1 at Larissa.
By the time their game had started, Panathinaikos, the only team that could still catch them, had already been beaten 1-0 by Iraklis, so handing Olympiakos the title.
It is the 34th championship in Olympiakos' history and qualifies them for next season's Champions League.
It also means they are one game away from collecting their 12th league and cup double - they face AEK Athens in the Greek Cup final on May 6.
