Antoine Griezmann's penalty handed Atletico Madrid a slender 1-0 advantage over Leicester City in the first leg of their Champions League quarter-final on Wednesday.
In a game of very few chances, Griezmann proved decisive as it was he who also won the penalty with a lung-busting run from well inside his own half before being brought down by Marc Albrighton midway through the first half.
The French international put his previous penalty demons behind him to convert from the spot and put Atletico in the driving seat for a third semi-final in four seasons.
However, Leicester still have reason to believe their dream run on their first appearance in the Champions League can continue when the sides meet again on April 18.
Unusually for Diego Simeone's men they were in almost complete control of possession, but largely limited to shots from long range.
Koke came closest from distance when he drilled an effort off the outside of the post after just five minutes.
Yannick Carrasco then slashed wildly at a volley when well-placed at the back post.
Griezmann and Saul Niguez were next to take aim from outside the box, but both failed to find the target with powerful drives that flew over Kasper Schmeichel's goal.
Leicester had been enjoying their best spell of the half when suddenly they were caught short-handed at the back on 27 minutes.
Griezmann collected the ball outside his own area and ran to just inside the Leicester box before being crudely barged over by Albrighton.
Schmeichel had saved a penalty in each of Leicester's two legs against Sevilla in the last 16 and Griezmann had missed his last four for Atletico, including in last season's Champions League final.
However, Griezmann sent the Dane the wrong way from the spot to register his 24th goal of the season.
Both sides seemed content to settle the tie at the King Power in six days' time with Atletico holding a 1-0 advantage after the break.
Meanwhile, Borussia Dortmund coach Thomas Tuchel slammed the decision to play the first leg of their Champions League quarter-final against Monaco just a day after a bomb attack on the German team's bus.
Teenager Kylian Mbappe struck twice as Monaco claimed a thrilling 3-2 win at Signal Iduna Park on Wednesday, but Tuchel was furious at the way the incident was handled by governing body UEFA.
The fixture was postponed 24 hours after three explosions rocked the Dortmund team coach and left Spain international Marc Bartra with a broken wrist as the Germans made their way to the ground ahead of Tuesday's scheduled kick-off.
"We felt completely passed over, it came down to 'tomorrow, you’re playing'," said Tuchel.
"Ultimately, it was decided in Nyon in Switzerland whether or not to play the next day. It was a somewhat powerless feeling.
"Each player had the right to start with a somewhat queasy feeling."
