Chelsea were handed a boost in their bid to reach the quarter-finals of the Champions League after opponents Paris Saint-Germain lost for the first time since November.
Laurent Blanc's team had gone undefeated in 24 matches in all competitions winning 22 two of those including a 16-match winning streak between 4 December and 10 February - PSG's Ligue 1 record of unbeaten games ends at 36 stretching back to the end of last season.
It was only their second defeat in 42 games all season, the other a 1-0 defeat at Real Madrid in the Champions League on 3 November. It was the club's first loss on French soil since losing to Bordeaux on 15 March.
PSG hold a 2-1 aggregate lead over the Blues following the first leg in the Parc Des Princes, Zlatan Ibrahimovic and Edinson Cavani on target; John Obi Mikel scored a rare goal to give Guus Hiddink's team a vital away goal.
Chelsea, who themselves have lost just one in 15 since Hiddink took charge, welcome PSG to Stamford Bridge on 9 March.
Despite their 2-1 defeat to rivals Lyon on Sunday, where they trailed 2-0 at half-time, PSG are almost certain to win Ligue 1 for the fourth time in a row, and soon as they currently hold a 23-point lead over second-place Monaco with just 10 games, and therefore 30 points, remaining.
Lyon's goals came from teenage forward Maxwel Cornet and midfielder Sergi Darder, Lucas Moura scored in the second half for the Parisiens but it was not enough.
"Lyon played better than us, so congratulations to them," David Luiz said after the loss. "We didn't play very well tonight and that's football."Reuse content
