Premier League clubs have made limited progress on improving access for disabled fans, campaigners have said.
Thirteen out of the 20 sides are failing to provide the required number of wheelchair spaces, says the Equality and Human Rights Commission (EHRC).
It says only seven clubs have larger, fully equipped toilets, while seven clubs are breaking Premier League rules on providing information to fans.
The Premier League said clubs were working hard to improve facilities.
A BBC report in 2014 found that 17 of 20 clubs did not provide enough wheelchair spaces.
