Julen Lopetegui speaks with Pique.
"He told us five minutes before the press release", Rubiales said. "There's a way to act that needs to be fulfilled". However, Spanish FA president was staunch in following through on his decision.
"I saw it in the press, it had already happened, and because of my responsibility, I know that whatever I do, there will be criticism". "I have spoken to them and I can assure you that the players and the the new coaching staff will do everything possible to lead the team as far as possible [in Russia], but it's a complicated situation".
"To win is very important, to have the best coach is very important, but above everything is acting in the right way". We have been forced to make this decision.
