Defender Gary Cahill admitted Chelsea face a tough task to reach the semi-finals of the Champions League after they conceded a "horrible" late goal to lose 3-1 at Paris St Germain.
Substitute Javier Pastore was able to wriggle free of some lax defending and fire past Petr Cech's near post with the last kick of the game and leave Chelsea staring at elimination ahead of next week's second leg.
"It was a horrible time to concede," Cahill told Sky Sports 1.
"It's a sloppy goal and unlike us. It's a big blow at 2-1.

"It was difficult to come here; 2-1 would have been okay to take to Stamford Bridge. It's devastating."
Cahill's boss Jose Mourinho was more scathing in his assessment of the defending.
"He (Cahill) says sloppy. I say ridiculous," he added.
"We played against a great team, full of good players especially attacking players.
"You would expect them to score fantastic goals. Not the goals they scored."
