When Manchester United defeated Paris Saint-Germain in their opening match of the Champions League a year ago it arguably represented the pinnacle of Ole Gunnar Solskjaer as manager.
The Norwegian has had many other impressive victories as he nears three years as United boss but none were quite as jaw-dropping as the dominant victory at the Parc des Princes last October.
Instead of picking off their opponents with pace on the counter-attack United went to the French capital and dictated play against the previous runner's-up of the competition, it was a night in which the Norwegian really did act like an elite manager.
United fans will also re-call an incredible performance from academy graduate Axel Tuanzebe who filled the boots of absent captain Harry Maguire by subduing the threat of World Cup winner Kylian Mbappe and nullifying the Paris Saint-Germain attack.
Another key component of the win was the performance from Alex Telles on his debut, though few fans thought that night in Paris would also represent his zenith in a United shirt.
The Brazilian made his first appearance for the club that night having recently signed from FC Porto and was at the heart of United's attacking threat in a wing-back role on the left.
Telles, 28, embraced his attacking freedom to attack the PSG defence and was unfortunate not to finish the match with an assist after twice finding Scott McTominay with balls into the box. The wing-back also shone with his set-piece delivery and added an extra element to the United attack which contributed enormously to their imposing style of play.
Many supporters thought it would spark a new era at Old Trafford, but less than a year after arriving Telles already looks like a player who is surplus to requirements given the resurgent form of competitor Luke Shaw.
The England international started the win over PSG in an auxiliary centre-back role but would soon recapture his left-back berth after a revitalised run of form which saw him reach world-class status.
Despite all the initial hype, Telles has only made 25 appearances for United and his only appearance this season saw him torn apart by Ryan Fredericks for the West Ham winner last week. The mitigation to that dire defensive display was that he was making a rare start in a makeshift backline and probably needed a slower start to get him back up to match speed rather than the scenario which he was thrown into.
Regardless of the circumstance, Telles will be eager to put things right as soon as possible and against Villarreal on Wednesday night he could have the perfect shot at redemption.
Shaw is a doubt for the match after his early withdrawal in defeat to Aston Villa at the weekend and even if passed match fit he looks in need of a rest after a gruelling calendar year which saw him largely undroppable for both club and country.
While the English full-back remains the first-choice selection it is in United's own interests to ensure his back-up replacement is also match fit and raring to go just in case his form continues to suffer in the weeks ahead.
“I’m really happy with my first season at United and I’m sure that next season will be even better," Telles insisted when quizzed by club media in the summer.
“I think I always took the opportunity to do my best whenever I was on the pitch. I had good games, with the adaptation process the first season isn’t easy, but I believe that when Ole gave me the opportunity and placed his trust in me and put me on the pitch, I did my best.
“I’m sure that I’ll continue doing even better to spend more time on the pitch and get a lot more minutes.”
With only one appearance so far this season, Telles is a long way off fulfilling his summer target but his struggles at Old Trafford have as much been about the success of Shaw as his own failings as a player.
This week should provide the perfect chance to prove he is really worthy of regular playing time, now it is down to Telles to make sure he takes it.
If not, at least we'll always have Paris.
