Chelsea football fans are demanding action, after it’s emerged their chairman’s an investor in a controversial ticket resale website.

Todd Boehly has a stake in Vivid Seats, which the Premier League lists as “unauthorised”.

We have found sellers on the site were offering tickets for one match for twice the cost of a season ticket.

These supporters at Stamford Bridge are frustrated.

Vivid says sellers on its website set ticket prices – and that it doesn’t make any revenue.

Officials at Chelsea declined to comment.
