Sevilla veteran Sergio Navas felt they were robbed in defeat at Real Madrid.
Luka Modric scored in the 81st minute for Real's 1-0 win.
"The team fought, in the end they scored the goal and we have to continue. I think that action was offside," Navas briefly commented to DAZN.
Minutes later he insisted to Sevilla's official media, the midfielder stated: "We saw that action very quickly, but I think one of their players is offside.
"He's in the way and our player clears when he sees the opponent's situation, in the end he intervenes."
With a displeased expression, Navas concluded by saying: "For it to escape like that is a shame and one cannot be happy."
