Diego Simeone has warned his Atletico Madrid defenders to be on guard over Jamie Vardy's frenetic pressing, insisting any mistakes will be pounced on.
The Atletico manager was full of praise for the former non-League striker, who scored his first Champions League goal on his last match in Spain.
Vardy played a pivotal role in Leicester's progression past Sevilla in the last-16, finding the net in the away leg then antagonising Samir Nasri into aggression that saw him sent off.
Vardy, who scored 24 Premier League goals last season, has overcome a barren spell to score seven in his last ten games for club and country.
