Ole Gunnar Solksjaer's men sit 14 points shy of their city rivals after a forgettable visit to Selhurst Park that saw them dominate the ball but do little with it.
Here's how the players from both sides rated...
✔️ GOOD PERFORMANCE
Dean Henderson: 6.7
With David de Gea absent due to personal reasons, Dean Henderson was given another chance to impress in the United goal.
And, while the Englishman only had two saves to make all evening, his brilliant late stop from Patrick van Aanholt secured the visitors a point.
The Dutchman may well have been ruled offside had the VAR lines been needed but it was an incredibly tight one and a potential key moment in the game for the visitors.
Henderson can't do much more to show that he is ready to take on the No.1 jersey.
✖ BAD PERFORMANCE
Edinson Cavani: 5.8
Brought into the starting XI in the absence of Anthony Martial, Edinson Cavani failed to take his chance in the capital.
The Uruguayan managed just 23 touches of the ball - fewer than any other starter apart from Henderson - and, while five of those were in the box, he only managed two off-target shots.
Cavani will have to do more if he is to earn a regular starting spot.
⭐ STAR MAN
Joel Ward: 7.5
Although they will have faced far tougher defensive examinations in the past, Palace's work at the back was still praiseworthy.
And Joel Ward was key to that, winning four of his six duels, making seven clearances - including one particularly brilliant sliding challenge to cut out a cross - and a match-high eight recoveries.
The Englishman deserved his clean sheet.
