English football clubs are being warned they will face “enormous opposition” if they try to introduce dynamic pricing for match tickets – after two top sides in Spain confirmed they were adopting the controversial practice.

Valencia and Celta Vigo are believed to be the only European clubs to have embraced the system for this season’s matches.

Although there are no suggestions dynamic pricing will be introduced into the English game, there has been growing concern clubs are vastly hiking prices, depending on the level of opposition.

It also comes after the huge controversy surrounding the sale of tickets for next year’s reunion shows by Oasis – where dynamic pricing saw tickets worth £148 being sold for £355 within hours of release.

The Football Supporters Association (FSA) warned against “greedy owners in football” trying to “exploit supporter loyalty” in the English leagues.

In a statement, the FSA said: “With impeccable timing after the Oasis fiasco, voices in football have started to float the idea of infecting football with dynamic pricing.

“Never underestimate the potential for the most greedy owners in football to try and import terrible ideas from other industries to exploit supporter loyalty.

“Match-goers are already mobilising against the recent wave of price rises and attacks on concessions. Any underhand increases will be met with enormous opposition.”

The FSA said it is also concerned over how 19 of the 20 Premier League clubs raised prices over the summer.

Valencia said it had the support of Spain’s top league – La Liga – to introduce dynamic pricing.

In a statement, the club said: “One of the new features for the 2024/25 season is the implementation of dynamic prices when purchasing tickets.

“Following the global trend established for shows, sporting events and entertainment, Valencia CF will use this practice that has the support and technology of LaLiga.

“Tickets will go on sale with a base price, which could increase as the days go by, subject to different parameters such as the occupation of the stadium area and the proximity of the date, among other factors.

“Buying your tickets early ensures you the best section and the best price.”
