Unai Emery's men were crowned Europa League champions after beating Freiburg 3-0 on Wednesday, ending a 30-year drought without a major trophy.
Aston Villa then somehow recovered from their celebration-induced hangover to secure a 2-1 win over Manchester City on the final day and a fourth-placed finish in the Premier League.
A brace from Ollie Watkins, who was recently called up to England's World Cup squad, cancelled out Antoine Semenyo's opener and sent the away corner of the Etihad Stadium into ecstasy.
Following that incredible result that spoiled Pep Guardiola's final game in charge, captain John McGinn has reflected on what has been a "special" campaign for everyone involved.
"That yesterday summed up what is a special group of players!" McGinn exclaimed in a post on X.
"The season has come with its challenges and difficult moments but a top 4 finish and a trophy makes it the most special one yet! Thanks for the unbelievable support throughout the season both home and away! Can’t stop laughing at Ollie scoring 2. See you soon UTV!!"
McGinn was instrumental to Villa's best campaign in three decades, and he will now lead his side back into the Champions League.
