Spain coach Vicente del Bosque admits rowing with Barcelona midfielder Xavi.
Xavi is unhappy with Del Bosque's rotation policy during the Confederations Cup.
"Unanimity is impossible and it's quite normal for someone to object or disagree with what we do," Del Bosque highlighted to Onda Cero.
"We had made certain plans for the Uruguay game, so we have nothing to worry about.
"Regarding Xavi, we have spoken with him and we have had some disagreements, but he has never named names. It's not a sign of weakness; it's a sign of strength.
"The person in charge should have the humility to listen to others."
