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.
Griezmann’s first-half masterclass
The technical quality of Atletico’s players was matched by a shrewd tactical plan from manager Diego Simeone that sought out the space Leicester tried to deny them.
Griezmann – reputedly a summer target for Manchester United – popped up between the lines, with midfield anchorman Wilfred Ndidi and the two centre-backs uncertain who was best placed to pick him up.
It was the France international’s more obvious quality that earned Atletico the opener as his searing pace spread panic in the Leicester defence and Albrighton bundled him over.
Referee Jonas Eriksson pointed to the spot despite Leicester’s protests and Schmeichel could not produce a third penalty save after his two in the tie against Sevilla.
The German will be suspended for the second leg and, with captain Wes Morgan not yet back from injury, boss Craig Shakespeare will have to make do and mend in the centre of defence on the biggest night in the club’s history.
