PAOK Salonika won the Greek Super League title for the first time in 34 years after beating Levadiakos on a day of high emotions at Tomba Stadium.
Home fans celebrated a day early with a march along the northern city’s promenade before continuing the revelry after the final whistle.
The port-city club will finish the season unbeaten if they defeat Giannina in their final fixture.
Second-placed Olympiakos, winner of 44 titles, are eight points behind.
PAOK, who won the league in 1976 and 1985, have their sights on a domestic double as they go into their Greek Cup semi-final second leg match against Asteris Tripolis with a 2-0 lead.
