Real Valladolid owner Ronaldo Nazario says Barcelona shouldn't blame coach Ernesto Valverde for their Champions League elimination by Liverpool.

The Blaugrana's 4-0 defeat against Liverpool at Anfield saw the Catalans crash out of the Champions League in embarrassing fashion for the second year in a row, and the former Brazil striker is adamant that the other players deserve respect.

"Barcelona have a great team, and they have the best player in the world in Messi," Ronaldo said at an event for Santander Bank.

"The other day I heard that when they lose, it's because of Valverde, Coutinho... but not Messi.

"And when they win, Barcelona win because of Messi.

"It's a tremendous lack of respect to all the players and the coaching staff."
