La Liga president Javier Tebas has defended the inclusion of Friday and Monday nights for the new season amid fresh criticism.
Spanish FA Luis Rubiales last week hit out at La Liga for scheduling matches in both of the time slots, which are highly unpopular with fans.
Rubiales claimed that Friday night matches could only be played with prior agreement between the league, the FA and the clubs involved, while Monday night games should not happen at all.
Rubiales cites the Ministry for Culture and Sport as also having a saw on the controversial matches, which numerous fan groups are desperate to eliminate ahead of the new season.
“These are the hours that there are,” Tebas said, as cited by Diario AS, during the presentation of the sponsorship agreement between 'Deliveroo' and his agency.
“You can ask for a 'Deliveroo' on Fridays and Mondays while we watch a match…”
The nature of Spanish culture means that night matches during the week are tough for fans to attend, particularly those making trips to away grounds.
There have been numerous fan campaigns calling for both fixture slots to be pulled from the calendar with a full concentration of matches around Saturdays and Sundays, making the calendar more streamlined.
