And it's not the first time the Hammers chief has messed up in such fashion on Twitter. Indeed, when welcoming Pedro Obiang over the summer, he tweeted a picture of Angelo Ogbonna, who the east London club later signed anyway.
For Nottingham Forest fans, there was plenty of laughter at Gold's latest gaffe. And yet Forest supporters will also be understandably frustrated.
Despite leaving the Championship side on Deadline Day, the 25-year-old is still Nottingham Forest's top scorer. He was a key player - now his own co-chairman can't even recognise a picture of him.
More social media embarrassment for Gold, then, this time brings some form of humiliation to one of West Ham's players. Here's how Nottingham Forest supporters reacted on Twitter to Gold's Antonio mess-up:
It's November and Michail Antonio, who we sold on the 1st September, is still our top scorer. #NFFC— Tom VVardle (@tomvvardle) November 5, 2015
Too much is being made about #whufc chairman David Gold not recognising his own player Michail Antonio!— Domenic Brunetti (@domthered) November 5, 2015
