Deportivo coach Gaizka Garitano was left fuming at Sergio Ramos' late winner for Real Madrid, suggesting the officials would have played for as long as it took the hosts to score.
The Galician side pushed Madrid to the wire on Saturday, and entered stoppage time at the Santiago Bernabeu tied at 2-2.
Ramos, however, repeated his heroics against Barcelona with another decisive late goal in the five minutes of stoppage time added on by the fourth official, to the dismay of Garitano.
"[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," he fired to reporters.
"In the Bernabeu there is more added time, until Real Madrid score the final whistle doesn't blow."
The win keeps Madrid six points ahead of Barcelona, who kept up the pressure with a 3-0 win away to Osasuna.
