Manchester United and Tottenham Hotspur’s handicap fans criticized the number of wheelchair votes available in the Europa League final as “insult” – both clubs both earned 26 tickets in the Bill Barço Stadium’s nearly 50,000 box offices.

United's Association of Disabled Supporters and Spurs, representing a fan base of disability supporters, expressed anger at the scale of the allocation, which includes 15,000 tickets per club, including 15 "easy access" seats.

In response, competition organizer UEFA said it offers 75 wheelchair locations at St. Mams Stadium – including neutral space and features free companion seats and guaranteed sight.

UEFA said 15% of those tickets were still unsold and available for purchase as of Tuesday morning. Both fan groups have objected to the BBC Sport.

The stadium is home to Spain's top track and field sports, with a capacity of over 53,000 but has been reduced to 49,600 in Wednesday's final.

The stadium is usually able to host 208 wheelchairs and 102 easy access seats. This is slightly below the rules recommended in the European rugby company's own size stadium guidelines.

But the two supporter groups and competitive venues at the disabled sports charity level calculate that even in the St. Mams restrictions, the two clubs should still have 58 wheelchair space and another 28 easy access tickets.

Spurs ability member Mark Spencer suffered a spinal injury but was not in a wheelchair. He took a bus to Bilbao and had no tickets to watch the game in the fan park.

He told BBC Sport: "It's an understatement to say I can't go to Madrid to compete in the Champions League (finals) in 2019 and I think it might be my chance - but UEFA just didn't give us a percentage of seats because they should bring us according to their own rules and regulations.

“You feel like you’re blocked from watching football and supporting your team due to your disability, so it’s very insulting and disappointing.”

"UFA ultimately has a responsibility to football fans to support your team. This should include people with disabilities," said Rick Clement, secretary of the Manchester United Disabled Persons Association.

Dr Rita Egan, another member of the Spurs' ability, said the group was "frustrated" by the allocation and accused UEFA of "ignoring" the complaint for not responding to the letter.

Level Competition Director Tony Taylor said: “We saw another defeat at a fair event by European Football Club.

“There was a lack of accountability before, and now we can see more disregard for fans with disabilities, which ignores the governing bodies’ own guidance and makes use of the available facilities without good reason.”

In response, UEFA said it “works to improve standards and experience” for disabled fans, taking into account “visit quality,” “historical needs” and the ratio between capacity and accessible seats.

It noted that 59 of 60 allocated seats were sold in the final of the same stadium last year, with only 41 of 93 seats between the men's Europa League final last season and Baylor Leverkusen allocated in Dublin.

UEFA also told BBC Sport that it "investigated the solution" to obtain easier seats and spoke with disability access officials from United and Masturs.

European Football's governing body added: "While both suggest they can sell more easily available tickets, they also expressed a tendency to maintain current allocations rather than increase the quantity at the expense of seat quality."

The BBC Sport has approached two clubs to comment.
