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 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.
