Chelsea ended a run of three consecutive defeats to rivals Barcelona with a 1-1 draw in the Women's Champions League.
Sonia Bompastor’s team went ahead after 14 minutes at Stamford Bridge through Ellie Carpenter, but Ewa Pajor levelled shortly afterwards before a stoppage took place due to technical difficulties.
When play did get back under way, a cagey second half followed until a dramatic finale as Chelsea substitute Catarina Macario headed in with her first touch only to be denied by the offside flag in the 83rd minute before Carpenter dragged a gilt-edged chance wide.
It meant the hosts had to settle for a point against a team they have now defeated once in only eight meetings.
Chelsea are down to sixth in the league phase after four fixtures and outside of the top four which will earn automatic qualification for the quarter-finals.
Elsewhere, Atleti hammered Twente 4-0 in Enschede, while Bayern München were 3-1 winners at Paris SG.
OH Leuven and Roma played out a 1-1 draw at the Den Dreef stadium in Belgium.
Bayern München, Barcelona, Wolfsburg and Manchester United have joined OL Lyonnes in being confirmed in the quarter-finals or knockout phase play-offs.
