German champions Bayern Munich have agreed a 10-year contract extension with kit manufacturers Adidas worth £645m, according to the Guardian.
Bayern already had five years to run of the old agreement with Adidas, but the German-based company have wasted little time in sealing a new deal.
The relationship between the club and Adidas will now run until at least 2030 and the deal was announced shortly before Bayern's DFB-Pokal defeat to Borussia Dortmund on Tuesday night.
Pep Guardiola's side lost the clash on penalties after drawing 1-1 after extra time, with Bayern missing all four of their spot kicks to miss out on an unprecedented treble. Robert Lewandowski scored to give Bayern the lead at the Allianz Arena, though Pierre-Emerick Aubameyang struck to force a shootout.
Philipp Lahm, Xabi Alonso, Mario Gotze and Manuel Neuer each missed from the spot to send Bayern out. Nevertheless, it was not all bad news on the day for Bayern, who have secured some more hefty financial backing.
Adidas owns 8.33% of Bayern, and spokesman Oliver Brüggen said of the new agreement upon its announcement: "With this extension of the contract until 2030 Adidas will continue its long partnership with FC Bayern München."
He added that they would "in the future continue to work on co-operations with top teams and federations in international football."
The new deal is substantial, but the figure is well below the deal Adidas agreed with Manchester United last summer. Adidas will supply the kits for the Old Trafford club from next season instead of Nike after confirming a £750m 10-year-deal - though United will still be wearing their current jerseys throughout their summer tour of the United States.
Bayern have already tied up the Bundesliga title, but will be looking to bounce back from their latest on-field disappointment by beating Barcelona in the Champions League semi-finals.
