Juventus has renewed its sponsorship agreement with Fiat to 2021.

The Serie A champion announced on Thursday that it signed a new six-year contract, which will begin with the 2015-16 season.

Juventus says the new deal is worth 17 million euros ($22.75 million) per season plus variable bonuses based on the club's results in national and international competitions.

As it has been doing since 2012, Fiat will operate as the club's sole shirt sponsor in all competitions, as well as supplying vehicles for promotional purposes.

Juventus won its third successive Serie A last season.
