In some respects, Everton fans might have been a little happy to see Cristiano Ronaldo find the back of the net in the dying seconds of Manchester United's latest Champions League clash.
Having lost disappointingly to Aston Villa last weekend thanks to a late goal and an even later missed penalty from Bruno Fernandes, the pressure on what was to follow for the Red Devils had grown.
A strike in the last minute from Ronaldo could have lifted that mood somewhat, but it wasn't exactly plain sailing on Wednesday evening.
Blues supporters might have been watching Ole Gunnar Solskjaer's side rather closely in midweek as they took on Villarreal in a repeat of last season's Europa League final.
If United had lost, the pressure would have been so great at the weekend that there could have been a huge reaction from the hosts at the expense of Rafa Benitez's side.
Ronaldo's late strike potentially solved that issue but the Spanish club, despite their eventual defeat, might have shown Everton what they need to do to cause some problems on their travels at the weekend.
In a similar way, Aston Villa did the same with their result against United a few days previously - winning thanks to a Kortney Hause header two minutes from time.
Dean Smith's side missed a number of great chances before the goal eventually came, with Matt Targett blazing over the bar when inside the area and Ollie Watkins being denied by David De Gea.
Villa then were able to take advantage from a well-delivered set piece, with Hause making a great run to the near post to firmly dispatch the header into the back of the net.
Everton are still yet to score directly from a set piece in the Premier League so far this season, but perhaps with Harry Maguire set to miss this weekend's game if could be a route that the Blues look to exploit.
But, Villarreal took things on a little bit further, despite not being able to take all three points in their Champions League group game.
In truth, Emery might be ruing the fact that his side didn't win.
In the first half particularly, De Gea was called into a number of excellent stops to deny Arnaut Danjuma and Paco Alcacer in particular.
Not over-awed by the occasion or their setting, the visitors managed to take the game to the hosts on numerous occasions before they deservedly took the lead after the break.
Villarreal ended Wednesday's match with more shots than their opponents, but were left to rue those missed chances come the end of the 90 minutes.
With something of a makeshift back four in front of the goalkeeper thanks to some injuries, the Spain international had to be on top form to keep his side in the game.
And it paid off as a spectacular Alex Telles equaliser was followed in the dying minutes by Ronaldo's winner to lift the spirits at Old Trafford once again.
Having lost to Aston Villa and exited the League Cup at home to West Ham in recent matches, United really needed to get back on track as soon as possible.
But the hints are there for Rafa Benitez and Everton.
They can't let the hosts this weekend rest on their laurels and believe that they will have an easy match once more, this is a chance for the Blues to really make a statement this season.
In their last two matches on their travels, in admittedly different capacities, Benitez's squad have been left hugely disappointed after two defeats.
The win over Norwich was a good way to get back on track, but this trip to Old Trafford is going to be the biggest test of the season so far.
What Villarreal in particular have proven, however, is that United can be attacked - there are chances in the game for Everton.
The need to be solid at the back with the attacking talent of Ronaldo, Fernandes, Mason Greenwood and more is clearly evident - and that will be a priority for the manager.
But having not seen an Everton win at Old Trafford since 2013, fans will be desperate to see their team pick up all three points. Recent wins for Villa and West Ham prove it is possible.
The Blues fought back admirably last season to earn a 3-3 draw in the dying moments thanks to Dominic Calvert-Lewin, who they are still set to be without this weekend of course.
Add Richarlison and Seamus Coleman to the list of absentees and it certainly will not be an easy ride for Benitez's side when they make the short trip down the East Lancs.
Being solid defensively must be at the heart of Everton's display, but attacking influence can't be allowed to fall by the wayside.
Villarreal played with little fear in large stages on Wednesday, and Benitez's squad can certainly do the same.
The visitors can create chances this weekend, they've had a lot of proof over the last few weeks of that fact. But, they need to take advantage of those opportunities as much as possible.
Do that, and there's no reason to suggest the Blues can come away with a promising result from a ground they usually don't have much luck visiting.
