Ronald Koeman read a defiant three-minute statement and then left room At the pre-match press conference on Wednesday.
The Barcelona boss refused to take questions from the media and asked fans for “patience” as the club “rebuilds”.
Speaking ahead of Barcelona’s LaLiga match against Cadiz on Thursday, Koman said: “The club is with me as a coach in a state of reconstruction.
“The financial position of the club is linked to sporting performance and vice versa.
“It means that we, as a team, have to rebuild the football team without being able to make huge financial investments. It takes time.
“Today’s young talents can become new world stars in just a few years.
“The good thing about rebuilding the team is that young players will have opportunities like Xavi and Iniesta who were in their time.
“But patience is required.”
