Spain Under-21s were left fuming after a 0-0 draw with Italy on Saturday that saw three players sent off, including Barcelona defender Oscar Mingueza.
The 21-year-old was dismissed on his international debut in a controversial incident in the 86th minute, although it looks a poor call from the referee who was just a meter away.
Italy duo Gianluca Scamacca and Nicolo Rovella also saw red late on as the game ended all square in Slovenia.
Spain Under-21 boss Luis de la Fuente made it pretty clear how unhappy he was after the final whistle.
“The replays show that Óscar Mingueza does not touch the Italian player. We are going to appeal the red and see how far it ends up going. Hopefully justice will be done,” he said.
“The players were unhappy. When you try to play a certain style of football and the opponent does things that aren’t exactly sportsmanlike... I was angry, and so were they.”
The draw leaves Spain top of Group B on four points after two games played. The team is due to play again on Tuesday against the Czech Republic.
