Other options are available, with a few tickets for sale in category 1 for a maximum of £ 17,054.
Furious Fans were quickly beating the prizes, with one writing on X: “Everything wrong with football at the highest level there.”

Sunsport has contacted Chelsea for comment.
The American businessman Boehly became minority owner at Chelsea in May 2022.
The 51-year-old is a director and investor in lively seats, a role that is recently described as a “conflict of interest” by the Chelsea supporters Trust.
Vivid Seats, which has its basis in Chicago, is legally permitted to operate abroad, but is forbidden for use by British users.
Boehly's Eldridge Industries own 41 percent of the Ticket resale site, according to IQ.
In an open letter written in March, the CST wrote to the Premier League and asked them to “act and investigate” in an attempt to clamp ticket on Chelsea Games.
The letter was: “Many CST members are clearly furious with this connection and have written us.
“As director of Chelsea FC and co-owner, Mr Boehly's connection with lively seats is completely inappropriate and undermines the efforts of Chelsea FC, the Premier League and the Metropolitan Police to considerably fight ticket pits.
“Mr Boehly was directly contacted by the CST and has offered several options to tackle both the concerns of both the public and private life.
“Neither Mr Boehly nor his representatives have acted on these requests, and thousands of tickets remain for sale on the Vivid Seats website.”
A spokesperson for UEFA said to Sunsport: “UEFA is strongly advancing from fans not to buy tickets on the secondary market.
“Ticket sales to the general public and fans of the teams who have reached the final are exclusively performed by UEFA.”
