Leicester City kept Atletico Madrid within reach as they restricted the dominant Spaniards to a single goal in their Champions League quarter-final first leg.
Koke had already hit the visitors’ post in the first half when the referee judged Marc Albrighton’s foul on Antoine Griezmann had been inside the penalty area.
Replays showed contact was made outside the box but Griezmann duly stepped up to send Kasper Schmeichel the wrong way.
Fernando Torres slipped as the goal beckoned in the second half but, that chance apart, Atletico struggled to carve out clear-cut openings against a stubborn Leicester defence.
Robert Huth – who will be banned for the second leg after being booked – saw a shot blocked and Shinji Okazaki narrowly failed to make contact with a low cross in the best of Leicester’s rare raids forward.
Atleti had the better of possession and chances throughout the second half, with Fernando Torres slipping and slicing a great chance well wide in the 61st minute after being played in by Koke.
Leicester continued to press for an away goal — after Jamie Vardy’s strike in Seville in the round of 16 proved decisive in the tie — but Atleti’s resolute defence dug in and offered no purchase for Craig Shakespeare’s team.
The two clubs will meet again on Tuesday, April 18 in Leicester for the second leg to determine which team will advance to the semifinals.
