Atletico Madrid goalkeeper Jan Oblak has been slammed by football fans after an "embarrassing" moment in the second leg of the Champions League round of 16 clash against Chelsea.
The Blues went into the reverse fixture at Stamford Bridge with a 1-0 win from the first match in Madrid.
Atleti were desperate for a goal to fire them level in the tie and a had a couple of penalty shouts go against them in the opening half.
Chelsea captain Cesar Azpilicueta was perhaps the most fortunate not to give away a spot-kick when he momentarily grabbed at Yannick Carrasco in the penalty area.
Carrasco went down under the contact but the referee waved the incident away, with VAR deciding there was no clear and obvious error.
Atleti's Luis Suarez also appealed for a penalty after being forcibly knocked off the ball by Antonio Rudiger.
However, that was effectively as close as the visitors came to scoring in a disappointing first 45 minutes, that was made worse by a Chelsea goal on the counter attack.
Kai Havertz won the ball in his own half and fed Timo Werner down the left wing for Chelsea, with the German showing a wicked turn of pace as he raced upfield.
Werner then played an exquisite ball into the goal square that Hakim Ziyech fired home with his weaker left foot.
The tame shot squirmed under the body of Oblak, who was kicking himself for not getting more on the attempted save.
Oblak slammed over 'awful' attempted save
Chelsea's goal left Atleti with a mountain to climb in order to progress and Oblak facing fierce backlash from fans.
Long regarded as one of the finest keepers in the world, the Slovenian was savaged by viewers on social media.
The Azpilicueta incident in the first half was thrust back into focus late in the second half when Atleti were reduced to 10 men.
The visitors were pressing for a goal in the final 10 minutes of normal time when Stefan Savić was involved in a tussle with Rudiger, while waiting for a corner to be delivered into the Chelsea box.
Savić threw out an elbow that collected Rudiger in the ribs, with the Blues defender making the most of the contact as he went down in the box.
The referee showed no hesitation in issuing Savić with a straight red card for violent conduct, much to the dismay of the player and his teammates.
The incident effectively proved the final nail in Atleti's coffin, with the 10-man visitors needing two goals in the final 10 minutes to progress.
Substitute Emerson Palmieri then ensured Chelsea's progression to the quarter-finals after finishing off another flowing move from the hosts with his first touch of the ball.
The Italian raced onto a pass from Christian Pulisic and lashed a left-footed strike into the bottom corner of the goal to seal the 3-0 aggregate win and a place in the final eight of the competition.
