Oviedo and Espanyol players stood still in the first 15 seconds of their LaLiga clash on Friday in the first protest, demanding better transparency and dialogue from authorities.

Players of Barcelona and Villarreal, whose teams are scheduled to play in Miami on Dec 20, have been kept out of the initiative “to avoid the protest action being interpreted as a possible measure against any club,” the players’ union said.

“In view of LaLiga’s constant refusals and unrealistic proposals, the Spanish Footballers’ Association categorically rejects a project that does not have the approval of the main protagonists of our sport,” AFE said in a statement on Friday.

LaLiga confirmed earlier this month that Barca’s away game against Villarreal would take place in Miami, after European soccer governing body UEFA’s reluctant approval.

Real Madrid had opposed the decision in August, saying it could undermine football’s competitive balance.

Spanish soccer federation (RFEF) president Rafael Louzan on Thursday defended the decision to move the match, calling it a “reward for fans”.

The AFE said it wanted league authorities to share information, analyse the “exceptional characteristics of the project” and address the needs and concerns of the players.
