This was a typically aggressive and rugged display from the Uruguayan, who dominated his compatriot - Suarez for long periods and was commanding in the air.
Portuguese superstar Cristiano Ronaldo, however, scored a late goal that allowed Zinedine Zidane's men to avoid a setback and come away with three points.
After so many years of being indelibly linked with the raucous Vicente Calderon Stadium, there were fears Atletico's move to the newly-expanded Wanda Metropolitano could adversely affect the momentum they are given by their fabled home support. The Frenchman could have cost his team with a clumsy foul late on, but Lionel Messi's free-kick was saved by Oblak.
But Messi sent the free kick right down Oblak's throat.
In the 6th minutes of the second half, Marcelo could make the difference double but he failed. Atletico was outstanding both with and without the ball.
But that's exactly what happened last night as the five time Ballon d'Or winner struggled to recreate his Argentina heroics to get Barca a result against Atletico Madrid with the La Liga leaders reliant on a late Luis Suarez goal to grab a point.
And Messi would have another chance just past the 70-minute mark, the ball falling to him at the top of the penalty area only for his left-footed shot to skirt wide of the post when a equaliser looked the likelier outcome. He awkwardly danced through the Atletico defense in the very first minute, but couldn't quite sort his feet out in front of goal.
That proved to be the final bit of goal-mouth action in the half, despite Barcelona's dominance in the opening 45 minutes.
The perfect record, though, probably flattered Barcelona in the first place. His pragmatic and straight-forward approach continues to provide a breath of fresh air in a business all too often afflicted by caution. Amid unrest, criticism and rumors of decline, the Catalan giants have steadied themselves. And although he had claimed on arrival in 2013 that he was "here to help" the Argentine attacker, he believed he deserved much more credit than that which he had received for the famous "remuntada".
HIghlights of Barcelona's 1-1 draw with Atletico Madrid in La Liga.
Luis 6 - Usual attacking intentions inhibited by the necessity of defending against Messi, and did a decent enough job.
