And fans from promotion chasers Leeds United and Norwich City were going ballistic on social media.
United were heading top of the league after three goals from Billy Sharp.
But once the striker was subbed off the game turned.
Villa hit back with three goals within the last 15 minutes of the game.
And it means the Blades failed to move top of the table.
Fans of United’s promotion rivals were to say the least delighted.
“GET IN VILLA #lufc” one Leeds fan tweeted.
“UP THE VILLA,” another Whites supporter wrote.
And a third wrote: “Get in villa. The championship is by far the most entertaining league this year! #lufc”
Canaries fans were just as delighted.
One put: “Coming back from 3-0 down? No big deal, Villa. Standard practice at Carrow Road #avfc #ncfc”
Another said: “We are top of the league!!!!…..f*** off Sheff Utd….f*** off Wilder…..thankyou Aston Villa !!!!!!”
And a third put: “Thank you Villa! Never thought I would celebrate a Villa goal….. We are top of the league!”
