According to the Villa faithful, the 27-year-old was guilty of squandering match-winning opportunities more than once during the 0-0 draw.
Whether it was dallying for too long on the ball during a one-on-one, or missing from point-blank range, it's fair to say Agbonlahor didn't endear himself to the visiting fans - and they didn't hold back with their criticism.
The words 'terrible', 'incredibly poor' and 'embarrassingly bad' were just some of the comments dished out on Twitter after the game, while the 27-year-old was also handed the award of 'miss of the season' by one fan.
Boss Paul Lambert was similarly disappointed, telling reporters: “I thought second half there was only one team that looked likely to win it.
"I thought Leo [Bacuna] should have scored and Gabby should have scored - and I thought Christian [Benteke] should have hit it, rather than trying to pass it."
Benteke also came in for some flak from the Villa supporters - but not half as much as Agbonlahor, who suffered a night to forget both on the pitch and on social media...

Can't believe we never won that, Agbonlahor was terrible throughout that game— Jake (@JakeCarless97) February 11, 2014
Gabby Agbonlahor has been incredibly poor tonight! #avfc— AVFC Transfer Tweet (@AVFCTransTweet) February 11, 2014
Remind me again why we let Bent go out on loan? Agbonlahor? Weimann? Jesus wept. Even Benteke looks unlikely to hit the target.— Paul Edwards (@RentonSir49er) February 11, 2014
Agbonlahor's miss was so embarrassingly bad, I've turned off the TV and gone to bed. Good night.— Keiran (@theNolan89) February 11, 2014
Was Agbonlahor the main culprit during Villa's draw with Cardiff?
