Deportivo La Coruna coach Gaizka Garitano claims Real Madrid are given an unfair advantage from officials when they play at home.
Garitano's charges enjoyed a 2-1 lead over Zinedine Zidane's side on Saturday, but then conceded an equaliser from Mariano Mejia in the 84th minute before Sergio Ramos netted a winner in the dying seconds to deny the visitors a point.
Los Blancos were able to maintain their six-point lead at the top of La Liga thanks to the win, and a disillusioned Garitano didn't mince his words after the 3-2 defeat, insisting that an unfair amount of stoppage-time was tacked on.
"[Madrid] have a lot of power at the end, when five minutes are added on when there was almost no time we knew we'd play until they scored," Garitano said in a post-match interview.
"In the Bernabeu, there is more added time, until Real Madrid score the final whistle doesn't blow."
