Atletico Madrid's Champions League hopes hang by a thread after they were held to a 1-1 draw at home by Group C minnows Qarabag on Tuesday despite playing a large part of the second half against 10 men.

The home side had far more chances than the team from Azerbaijan in the first half but fell behind in the 40th minute when Spanish midfielder Michel rose to meet a corner and delivered too powerful a header for Jan Oblak to keep out.

Midfielder Thomas Partey equalised in the 56th minute with a thunderous long-range strike and Atletico were given another boost when Brazilian Pedro Henrique was sent off a minute later.

Yet despite laying siege to the visitors' area, Atletico could not find a winner and, to complete their miserable night, they also had their own defender Stefan Savic sent off for a second booking in the 88th minute.

Diego Simeone's side, Champions League runners up in 2014 and 2016 and semifinalists last season, are third in Group C on three points, five behind leaders AS Roma and four behind Chelsea.

It means Atletico now need to hope for something remarkable to avoid a group stage exit for the first time since returning to Europe's elite competition in 2013
