Manchester City have signed a three-year shirt sponsorship deal with cryptocurrency exchange OKX worth more than £55million.
The Premier League champions believe they are ready to break revenue records and capitalise on their Treble success.
That was made more likely by sealing a contract in the region of £18m a season for the sleeves on the men's and women's kits.
City have been charged with 115 alleged financial breaches by the Premier League, but chief executive Ferran Soriano lauded their increasing appeal.
'It's about hard work — we haven't done anything that was out of the ordinary,' he said.
