LaLiga president Javier Tebas says mending bridges with Real Madrid counterpart Florentino Perez is a non-starter.
Tebas fell out over Real Madrid's attempts to create a breakaway European Super League.
Asked about fixing the relationship, Tebas told Movistar: "A reconciliation with Perez? No, it's a cultural issue, of differences.
"It's like if you asked me, 'Is there any chance you would give me your house? Why not?'
"It's practically the same thing. We think too differently about European football, there is no possibility of an agreement between me and most of the Spanish clubs."
