Allardyce took his Sunderland side to Upton Park on Saturday.
Allardyce enjoyed four years with the Hammers, during which he oversaw their return to the Premier League from the Championship and revived their fortunes after a disheartening relegation.
The two parted ways last summer, with West Ham deciding that a change in style was needed ahead of their move to the Olympic Stadium in the summer.
And Gold has admitted that the football was not pretty under his leadership, but their main aim was promotion, something they told him during his first interview for the job.
"When we interviewed him, we said 'OK, we'd like you to come and manage our football club; the priority is to get us promoted’,” he told BT Sport.
"We'd just been relegated and of course he achieved that. OK, the fans didn't like the style of football.”
“If I'm brutally honest, it wasn't pretty at times, but we were in the Premier League and we're building upon that now."
It is certainly a prevalent argument at present that Allardyce deserves more praise for the work he did at Upton Park.
He ultimately left the club because of his failure to pay the ‘West Ham way’ but many have now suggested that doing so wouldn’t have seen them stay in the Premier League.
Indeed, he helped to establish them in the division once again, and has played a bigger part in their success under Slaven Bilic than some would care to admit.
