Bayern Munich's treble-winning former coach Jupp Heynckes has turned down Pep Guardiola's invite to help celebrate the club's historic fourth straight German league title this Saturday in the Bavarian capital.

Heynckes, 71, steered Bayern to the 2013 treble of Champions League, German Cup and Bundesliga titles before his successor Guardiola became head coach for the 2013/14 season.

The Spaniard continued Heynckes' success by steering Bayern to the German league title in each of his following three seasons in charge.

Bayern have won this season's Bundesliga title, making them the first club to win the German league title four years in a row.

But Heynckes has turned down Guardiola's invite to join the party this Saturday at the Allianz Arena, after the final game of the season at home to Hanover 96, in what will be the Spaniard's final home game before coaching Manchester City next season.

"Many thanks for the invite, but the party belongs to Pep," Heynckes told German daily Bild.

"Not just because of the fourth (straight) title, but also because it will be his farewell party."

Bayern were confirmed the 2015/16 Bundesliga champions after Saturday's 2-1 win at Ingolstadt, after which Guardiola made his invitation.

"Of the four championship titles, I only helped with one, so a quarter, Pep took the other three and that is a great achievement," added Heynckes, who turned 71 on Monday.
