Leverkusen - Bayer Leverkusen have one foot in the Champions League's quarter-finals following their shock 1-0 home win over last season's finalists Atletico Madrid, who finished with 10 men on Wednesday.
Hakan Calhanoglu's superb second-half goal in the last 16, first-leg clash means Bayer take a slender advantage to Atletico's Vicente Calderon Stadium for the return leg on March 17.
Reigning Spanish league champions Atletico played the last quarter of an hour with ten men after defensive midfielder Tiago was sent off for a second booking.
