The 29-year-old believes his opposite number's red card was the decisive moment in Saturday's Clasico loss at Camp Nou, but is not unduly concerned by the result
Gerard Pique believes the decision to dismiss Real Madrid defender Sergio Ramos of Saturday's Clasico effectively cost Barcelona the game as they lost 2-1.
Ramos received his second booking of the evening after a foul on Luis Suarez with the score at 1-1 seven minutes before the final whistle.
But Cristiano Ronaldo then somewhat surprisingly earned Madrid all three points with a goal just two minutes after the Spain international's exit.
And Pique admitted the Catalans imploded following Ramos' red card, stating his side surrendered control of the encounter.


"We did not know how to play with a player more on the pitch and we lost control after the red card," the defender said via Barcelona's official Twitter account.
Saturday's defeat leaves Barcelona just six points clear of Atletico Madrid in the Liga table, while Real Madrid are also back in the title race, now seven points off the pace.
Nevertheless, Pique sees no reason to panic as the Camp Nou side's 39-game unbeaten run in all competitions came to an end, stressing they are still in good shape to win silverware this campaign.
"We have to move on and not dwell on this defeat. You cannot always win," he continued. "We are still in a good position in three competitions."
Barcelona will be looking to return to winning ways on Tuesday, when they host Atletico Madrid in the first leg of their Champions League quarter-final tie.
