Spanish LaLiga club Osasuna has become the latest team to join the league initiative which sees away tickets capped at €30 (£26/$33).
A minimum of 300 seats at the 23,500-capacity El Sadar Stadium will be capped for away supporters.
Osasuna has joined a number of other Primera División clubs, including RC Celta, in committing to the scheme, which was made official in July. The teams backed the agreement proposed by supporters’ group Aficiones Unidas (United Support), matching the away ticket cap that already existed in the second-tier Segunda División.
In Italy, Serie A club Juventus said that it would be introducing a cap for away tickets to league and Coppa Italia games at Allianz Stadium.
In England, a £30 price cap on Premier League away tickets has been in place since the 2016-17 season.
Luis Sabalza, president of Osasuna, said: “We are delighted to join this LaLiga initiative, since Osasuna has always been in favour of encouraging the movement of visiting fans and we think it is a good idea to reach agreements so that prices are homogeneous.
“In fact, we already had the previous experience of the agreements with the Basque clubs, which were very satisfactory. So once we have guaranteed that our members and supporters will be the recipients of the tickets, we are delighted to join.”
