Cast your minds back to Project Restart and a very particular incident will come to mind when you think about Aston Villa.
When they faced Sheffield United, the Blades had a goal wrongfully disallowed that once all was said and done at the end of the season, would have relegated them.
Instead, the Villans stayed in the division and are now counting their lucky stars that they did.
The turnaround from Dean Smith and his players has been phenomenal and if you thought the 7-2 win over Liverpool was incredible, they then had the audacity to stick three unanswered goals past Arsenal.
The Gunners were flat, languid and tepid, completely indistinguishable from the side that beat Manchester United only a week ago.
They rarely created any chances and were completely outdone on the counter-attack. Villa's football was relentless and easy on the eye as they carved open Arsenal at will.
Rob Holding was given a torrid time by Villa's creative players and to make matters worse, Bernd Leno could do little for any of the goals. It was a sorry state of affairs for the London club on what was surely Mikel Arteta's worst night in management.
Earlier this summer, Arsenal rejected the chance to sign Lyon playmaker Houssem Aouar and thus, the performance of Jack Grealish against them on Sunday will rub further salt into the wounds.
He was an effervescent bubble of energy, taking the Gunners' defence to the cleaners. A video of his mesmeric performance can be found here.
Grealish ran riot and although he failed to find the back of the net, helped himself to an assist that led to Ollie Watkins' second goal and Villa's third of the night.
Arsenal supporters were quick to realise just how much he'd torn them apart, taking to Twitter in their droves to rave about the 25-year-old's display at full-time and during the match.
As you can see, despite suffering a crushing defeat, Arsenal fans couldn't help but stand up and take notice of Grealish.
He left quite the impression on supporters and it's clear to see why.
As well as grabbing an assist, Grealish managed five shots, performed two successful dribbles and was fouled on four occasions.
The England international also won six ground duels and played two key passes in a scintillating display of football.
It's hardly surprising that the playmaker was valued at around £80m in the summer.
