Sergio Ramos was left infuriated when Cristiano Ronaldo was denied a penalty after being brought down by Javier Mascherano, prompting Sergio Busquets to accuse Carlo Ancelotti's side of "crying to the referee."
Alves has now backed his team-mate's scathing view on the issue, telling reporters after the match: "Their referee complaints fit like a glove for not accepting defeat. If they had scored an equaliser they would not be talking about the officials.
"Maybe Ramos should not talk about the referee as he could have been shown two yellow cards. As players we are the least qualified to talk about referees."
The Brazilian also claimed that the media had distorted certain incidents from the game simply to bolster coverage of the clash at Camp Nou.
"The newspapers and TV have sold more copies to their audience for debating about the referee," he added.
Neymar's first-half strike and a stunning Alexis Sanchez goal settled the match on Saturday despite Jese Rodriguez's late consolation, moving Barcelona six points clear of Madrid in La Liga.
