Premier League champions Manchester City have signed a long-term kit deal with Germany’s Puma, replacing their current agreement with Nike.
The size of the deal was not disclosed, but media reports suggest it could be worth up to £65m a year for 10 years.
It will come into effect in July and also covers sister clubs in Australia, Spain, Uruguay and China.
Puma chief executive Bjorn Gulden said it was the biggest deal his firm had ever done.
He said Puma wanted to “maximise on-field performance as well as football culture, in areas such as music, gaming and fashion, to connect and inspire the fanbase of each team”.
Ferran Soriano, boss of the club’s holding company City Football Group, said: “It is a historic day for us. What we are doing has not been done before. It is an unprecedented partnership.”
