Manchester United put on an improved, largely entertaining display, but they could not deliver a win against Chelsea to ease the pressure on manager Louis van Gaal.
Van Gaal's position came under increased scrutiny after his men went on their worst run in 26 years, but his players came out fighting at Old Trafford on Monday.
United rattled the woodwork twice, but could not find the net and had to settle for their seventh goalless draw of the season.
Chelsea had their chances too. David de Gea pulled off stunning saves to deny Pedro, Cesar Azpilicueta and John Terry - and Nemanja Matic ploughed the ball into the East Stand after going through after the break.
But, United were the better side and probably deserved three points.
Whether that is enough to save Van Gaal remains to be seen. The statistics do not look good for the Dutchman.
United are now winless in eight, they go into the new year in their lowest position since the 1989-90 season and have scored two goals in their last four.
Some fans made it clear they wanted Jose Mourinho, rather than Van Gaal in the home dugout. One held a banner aloft imploring the manager to "Leave, Vanish, Go" and red Mourinho scarves were on sale from unofficial vendors outside the ground.
Van Gaal's self-doubt was clear to see after the Stoke defeat, but on Monday he strode down the touchline with his chest puffed out and head held high while waving to fans.
Whatever Van Gaal had said to his players before kick-off worked as their first-half performance bore no resemblance to the turgid, predictable displays so often seen here this season.
Just three minutes in, Wayne Rooney, restored to the starting XI, laid the ball off to Juan Mata, who hit the bar with a fierce volley.
The United skipper then provided Morgan Schneiderlin with a chance to score from the edge of the box, but his half-volley flew just wide.
This was thrilling stuff from the hosts, but Chelsea had their moments too. Willian swung over a corner which Terry met with a diving header. Luckily for United, De Gea saved athletically.
United continued to attack the Blues and had most luck down the flanks. Ashley Young and Matteo Darmian overlapped to cause Branislav Ivanovic and Azpilicueta problems. In the 12th minute, Darmian raced to the byline and sent over a dangerous cross, but there was no one there to convert.
Ivanovic was then turned inside out by Anthony Martial, who smacked a low shot on to the near post.
John Obi Mikel had to resort to illegal means to stop Martial. The midfielder stuck out a leg and halted the forward's pacy run just before the half hour.
Rooney was full of confidence. He took a touch before unleashing a fizzing drive which Thibaut Courtois did well to tip over.
The home supporters were enjoying this entertaining spectacle, but their team could not find an opener. Just after the break, they were biting their nails as Chelsea poured forward. De Gea saved brilliantly from Pedro and Azpilicueta in quick succession.
Then it was Courtois' turn to keep his team in it. The Belgian dived to his left to deny Herrera from point-blank range. Willian got away with a handball in the box as Chelsea cleared.
Matic was then presented with the best chance of the match when he raced through, but he skied over.
Rooney could have snatched the game at the death but he volleyed over. There was a smattering of boos after the final whistle, but no widespread dissatisfaction despite an eighth game without victory.
