Gold was sent a tweet by a prankster, asking to spread awareness of a ‘missing’ person.
The 79-year-old retweeted the post, and it then turned out that the ‘missing’ person was West Ham winger Antonio.
Gold, who has since deleted the tweet (a screenshot can be seen here), has explained his mistake.
“I read a tweet about someone who had a friend missing and I immediately wanted to do something about it, but initially didn't realise it was about Michail Antonio as I did it so quickly,” Gold explained on West Ham’s official website.
“I have spoken to Michail and he was not troubled by it. People have said I don't recognise him but that is nonsense.
"It was an error and the bottom line is that Michail is fine about it and he didn't for one minute believe I didn't recognise him. I see him on a regular basis.”
Struggling for playing time
Antonio has been struggling to get into the West Ham team since joining from Nottingham Forest in the summer transfer window.
The 25-year-old winger was one of the best players in the Championship last season, scoring 14 goals and creating 62 chances in 46 league appearances for the Reds.
However, the former Sheffield Wednesday man has played just 31 minutes in the English top flight for the Hammers, failing to score a single goal or create a single chance.
