Precisely as the United manager must have thought his fortune remained negative, his side delivered the home side's initial home loss in domestic football from February onward.
The Palace manager's players started strongly and deservedly took the lead via the French striker's second penalty attempt. However they failed to capitalize on their control and having failed to find the net at Selhurst, Amorim's team countered twice in nine minutes through the Dutch forward and Mason Mount.
The match proved disappointing afternoon at the end after multiple matches for the Palace boss, who observed his winger limp off with a worrying issue in the first period.
Ruben Amorim may have kept his emotions in check while walking down the tunnel directly following the final whistle.
The Portuguese coach dismissed comparisons between his and Glasner's tactical approach during preparation, while admitting that Glasner's team "simply perform things better than us|aspects superior to ours|elements more effectively".
The answer to the lacklustre defeat facing ten Toffees was to change the flank players, featuring the Ivorian moving to the right flank with the full-back replaced Patrick Dorgu.
Amorim's team probably recognized an opportunity to profit considering they enjoyed additional preparation time and almost went ahead after 43 seconds.
A long throw generated disorder in the Palace area yet remarkably Dean Henderson produced a point-blank save at his goal line to stop the Brazilian.
The near miss functioned as a warning for Glasner's men following the midday start that was dictated by TV requirements.
Quickly opportunities commenced appearing in quick succession. Following wasted a hatful of chances in midweek, it appeared it might not be the striker's opportunity as he pulled efforts missing the goal inside the opening 15 minutes.
Yet amid days during discussions about Mateta's contract extension hit obstacles, the French striker emerged who opened the scoring.
A further accurate delivery from Wharton enticed the young Frenchman into the challenge following an earlier superb interception to deny Yéremy Pino, the 20-year-old could only bring down Mateta within the 18-yard area.
The goalkeeper returned in a baseball cap to block the sun from the glare yet he'll feel regret to have allowed United to equalise eight minutes following halftime.
The home side was sleeping via a fast United dead ball enabling the Dutchman to chest the ball down and pivot in one motion to generate a strike that sailed into the far corner.
Following weathering a goalmouth scramble when the Dutchman nearly netted again at the wrong end, their afternoon got even better moments after when the Netherlands forward was brought down on the edge of Palace's box by the English center-back.
A temporary uncertainty developed among the defenders during Fernandes' delivery the free-kick to Mount enabling the Englishman to score past the keeper using a fierce strike.
Missing the Senegal international's acceleration to call on, Palace could barely muster another chance allowing Amorim's team to complete vital three points elevating the Red Devils climb above Palace to sixth position.
