Frank Lampard scored a last gasp winner for Chelsea in a feisty affair against Wolves at Molineux.
Ramires had given the Blues the lead shortly before the hour, but Stephen Ward equalised in the dying stages for the home side.
But Lampard grabbed all three points in the final minute of the allowed 90 to ensure Chelsea climbed into the top four of the Barclays Premier League.
Didier Drogba was left of by Andre Villas-Boas following an ankle injury, and Fernando Torres came in to replace the Ivorian striker with Juan Mata and Ramires playing the support roles either side of the Spaniard.
Torres started the first period brightly, but ill-discipline from both sides saw five yellow cards awarded in the opening 45 minutes.
Chelsea midfielder Lampard was fortunate not to see red for a dangerous looking tackle, while Torres bore the brunt of a number of challenges from the Wolves defence.
Wolves gave as good as they got during hour, but the visitors took the lead thanks to Ramires after he made the most of defensive hesitation to finish off a Juan Mata corner.
In a gesture of unity, the Chelsea players then all steamed towards Villas-Boas and the Blues coaching staff to celebrate with their beleaguered coach.
Wolves, though, continued to press for a goal, and it came with six minutes remaining courtesy of Ward.
Matt Jarvis chipped the ball to the back post, where Steven Fletcher headed across goal and Ward to hammered home from 12 yards out.
However, Chelsea left it even later to snatch a winner, and Lampard - who should not have been on the pitch - stole into the penalty box and finished expertly from Ashley Cole's pass.
