Bayer Leverkusen manager Xabi Alonso lamented his side's failure to hold onto a first-half lead at 10-man Atletico Madrid, who fought back to beat them 2-1 in the Champions League on Tuesday, saying his side lacked the maturity to cope with the pressure.

Piero Hincapie had put Leverkusen a goal up in the first half, following Pablo Barrios' red card for Atleti, which had looked like it put the visitors on course for victory

Leverkusen broke through in first-half stoppage time, Nordi Mukiele lofting a cross for Hincapie to head past Atletico goalie Jan Oblak. In the second-half, the early control evaporated as both sides played end-to-end, with Atletico using the chaos to equalise.
