Chelsea coach Jose Mourinho called his team's defending "a joke" after Paris Saint-Germain scored deep into injury-time on Wednesday to take a commanding 3-1 lead into their Champions League quarterfinal return leg next week.
A second straight defeat has turned the pressure back on Mourinho's Chelsea side, with big-spending PSG now favoured to reach the last four in the European Cup for the first time since 1995 and Liverpool grabbing the impetus in the Premier League.
"When the games are tight and when you make the defensive mistakes, you are in trouble," Mourinho said. "We couldn't transform these half-chances into goals and on top of that we made defensive mistakes, the kind of individual defensive mistakes, and we paid the price."
PSG substitute Javier Pastore capped the win with a brilliant goal in stoppage time. The Argentina playmaker gathered the ball on the right wing, cut inside and then jinked his way through the penalty area before planting a low shot inside goalkeeper Petr Cech's near post.
"It was a horrible time to concede," centre-back Gary Cahill told British broadcaster Sky Sports. "It's a sloppy goal and unlike us. It was difficult to come here; 2-1 would have been okay to take to Stamford Bridge. It's devastating."
Boss Mourinho was more scathing. "He (Cahill) says sloppy. I say ridiculous," later adding. "It's not a goal, it's a joke."
He also criticised his forwards, with neither Andre Schuerrle or his replacement, Fernando Torres, making any impression in the absence of the injured Samuel Eto'o.
Chelsea did well to contain Zlatan Ibrahimovic, PSG's top scorer with more than 40 goals this season. But Jose Mourinho's team was undone by lapses from captain John Terry and midfielder David Luiz, who gave the ball away leading up to the opening goal.
