Sportswear giant Adidas will pay up to €70m ($79m) per year in its extended sponsorship deal with the German Football Federation (DFB), according to the Sport Bild newspaper.
Although the two parties are yet to officially announce a deal, the newspaper said that the proposed new agreement will run for four years, from 2016 to 2019.
Adidas, which is believed to be paying €25m per year under its current deal with the DFB, will continue to provide playing kit to the Germany national team.
Adidas began its long-running partnership with the DFB in 1958, although rival sportswear company Nike was said to be interested in snatching the contract.
