Real Madrid coach, Carlo Ancelotti, was seemingly annoyed with the whistling of his players in Real’s 5-0 win over Rayo Vallecano on Saturday.
The Los Blancos bounced back from their recent two defeats, following goals from Ronaldo, Daniel Carvajal, Gareth Bale (2) and Alvaro Morata.
However, parts of the Real faithful used the opportunity to express their dissatisfaction with a couple of Real’s players, particularly Cristiano Ronaldo and Diego Lopez.
"I have always said that sometimes I understand whistles because they can be deserved," Ancelotti responded to the whistling of his players.
"Right now, no - the players are putting in a lot of effort. We need the help of everyone.
“Whistling Cristiano isn't comprehensible."
Ancelotti had declared that Diego Lopez remains his first-choice keeper for La Liga, while Iker Casillas will play in Champions League and Copa del Rey, but the fans jeered at the Spaniard whenever they could.
"Diego Lopez is focused on his profession and I don't think critics hurt him,” Ancelotti continued.
After two successive defeats, and victories by Atletico Madrid and Barcelona, the Los Blancos had to win to keep pace in the La Liga title race.
"Naturally this win is important," Ancelotti added.
"Today we reacted well following two losses. We played a great game, with a good attitude on the pitch.
“This serves to prepare well for the next game. In the last two games we made errors at the back. Today we didn't and we used the counter-attack well. The back four were good.
"We just have to think in ourselves and be positive."
Despite the whistling, Ancelotti remains convinced that the home supporters will rally behind their side when Borussia Dortmund visit the Bernabeu in the Champions League in midweek.
"On Wednesday, we'll have a great atmosphere at the Bernabeu because everyone is dreaming of the Decima [10th European Cup] and they know we can win if everyone gets behind the team," concluded.
"Together we can achieve the dream."
Cristiano Ronaldo has scored a goal in each of the last ten games he has played – nine for Real and one for Portugal.
