Tottenham have signed a new shirt sponsor deal with AIA, worth £320m over eight years.
The life insurance company has been on Spurs’ shirts since 2013, but the new deal is a significant rise in revenue for the Champions League finalists.
The deal matches the reported £40m Chelsea signed in 2015 with Yokohama tyres.
Manchester United’s seven-year deal with US car brand Chevrolet remains the biggest, worth about £50m per year.
AIA will continue to appear on the front of the club’s men’s, women’s and academy team’s shirts until 2027.
Spurs have recently opened their £1bn stadium, much of which was paid for with loans.
Despite that cost, in April they announced a world-record profit of £113m after tax for the 2017-18 season.
Earlier in July, Tottenham paid a record £53.8m for France midfielder Tanguy Ndombele, having not signed a player last season.
Asked if Spurs felt pressure to compete with their big-spending Premier League rivals, chairman Daniel Levy said: “If I’m honest, we don’t feel the pressure. Our view is wherever we can, we will improve the team.
“We have embarked in recent years on two very major capital projects, which I think in the long-term will be of great benefit to the club. We will continue wherever we can to improve the team.”
