Dominant Leverkusen upset the odds against Atletico

Bayer Leverkusen stunned last season's runners-up Atletico Madrid 1-0 in their Champions League round of 16 first leg on Wednesday courtesy of a fine strike by Hakan Calhanoglu.

The Turkey international scored the 57th-minute winner to set Leverkusen, who are struggling for form in the Bundesliga, on the way to their first ever win at this stage of the competition.

"This was a very, very good game from us," goalkeeper Bernd Leno, who twice rescued his team in the first half, told reporters.

"We showed a reaction to the criticism of the past week. We had some bad games but tonight we bounced back."
