The South American striker was involved in a couple of controversial plays, which could have been sanctioned with a red card by the referee.

Just when Luis Suárez seemed to have found his feet, he gets involved once again in controversial plays.

Prior to scoring a game-winning brace for Barcelona, the South American striker escaped a red card from the game's referee, as Barcelona's Number 9 kicked Atlético's defender Juanfran while the Spaniard cleared the ball away from his team's box. Minutes later, the game's ref decided to send off Fernando Torres, changing the course of the game.

But it wasn't all Suarez did to deserve a booking, considering his entanglement with Filipe Luis, who received a hard knock to his left cheek courtesy of Suárez's left hand. As Atletico's players demanded a red card, Suárez walked away unpunished.
