Just when Ruben Amorim likely believed his fortune would never turn, the Red Devils delivered the home side's opening Selhurst Park setback in domestic football beginning in February.
The Austrian coach's side had been rampant and deservedly took the lead through their forward's second penalty attempt. However they failed to make their dominance count after previously struggling to score against Palace, the visitors responded twice in nine minutes through their summer signing and the English midfielder.
This represented a difficult day concluding following a busy period for the Palace boss, who saw his winger depart hurt with a concerning injury before half-time.
His Portuguese counterpart probably contained his emotions in check while walking down the tunnel immediately after the match's conclusion.
Amorim had played down comparisons between both managers' strategic methods in the buildup, although he acknowledged that the opposition "are just doing things better than us|aspects superior to ours|elements more effectively".
His response to the disappointing loss against 10-man Everton was to change both wing-backs, including the young winger shifting to the right side with the full-back took over from Dorgu.
The visitors likely felt an opportunity to profit considering they enjoyed extra rest days and nearly scored first inside the opening minute.
A long throw created confusion in the home penalty box yet remarkably Dean Henderson made a close-range stop near the net to stop the Brazilian.
The close shave acted as an alert for Palace after the early kick-off that was dictated for broadcast purposes.
Quickly opportunities commenced appearing in quick succession. Subsequent to squandered a hatful of chances during European action, it seemed like could potentially not become Mateta's day after he sent attempts off target in the initial phase.
However during a period during discussions about the forward's renewal faced delays, the French striker emerged who provided the first goal.
One more perfect ball from the England international drew the defender toward the tackle and, having just made a brilliant block to deny Yéremy Pino, the young defender was forced to foul his compatriot inside the area.
The goalkeeper returned with head protection to protect his vision from the low sun however he'll experience frustration enabling Amorim's team to equalise eight minutes after the restart.
Palace were caught napping via a fast United dead ball and Zirkzee was able to chest the ball down while turning simultaneously to unleash an attempt that sailed into the far corner.
After enduring a goalmouth scramble as the forward came close again at the wrong end, their afternoon got even better a few minutes later as the Dutch attacker was fouled near the 18-yard line by Marc Guéhi.
A temporary uncertainty developed within the barrier during Fernandes' delivery the free-kick to Mount and that allowed him to score past the keeper via a strong shot.
Without Sarr's pace to depend on, Palace could barely muster further attempts allowing Amorim's team to see out an important win which moves United move above Palace into sixth place.
