The Hammers chief was hugely impressed by the 17 year old.
The 17-year-old midfielder was forced to plug gaps in central defence following an injury to James Collins.
But the task of operating in an unfamiliar role, nor the challenge of marking hefty striker Romelu Lukaku, put off the starlet as he turned in an assured display at Goodison Park.
Gold claims that Lukaku - who has 18 Premier League goals under his belt this season, including one on Saturday - is deserving of a world-class status, noting that Oxford's performance was all the better considering the Belgian's standing in the game.
“You look at Everton on paper and they have a fantastic group of players," the joint chairman told the Irons' official website.
"Lukaku is one of the best centre-forwards in the Premier League and up against a 17-year-old man in Reece Oxford, I thought he did very well coming up against a world class centre-forward."
It is not the first time that Oxford has made headlines this season, having dazzled in a 2-0 win at Arsenal on the opening day of the Premier League season when he was just 16.
He found first-team chances limited for a number of months after that, though he looks set for an extended spell in the senior set-up again, having also impressed in last week's 1-0 win over Spurs.
