The Champions League-winning former Hammers forward will go down in history as quite literally one of the club's biggest ever flops.
The ex FC Porto man played just 11 league games in East London after his move during Gianfranco Zola's spell as manager.
And it turned out to be one of the worst. The man who was South Africa's all-time leading goalscorer ballooned in size, barely featured and became something of a joke figure in the Premier League despite a hugely successful spell at Blackburn Rovers.
It got so bad, the club eventually agreed to pay McCarthy off to the tune of £1.5 million to terminate his contract, as reported by the Daily Mail at the time.
Acrimonious departure led to row
After his acrimonious departure from the English game in 2011, the 37-year-old was criticised by Brady and responded with an expletive-laden tirade about the West Ham chief executive - as reported by the Telegraph at the time.
At the weekend, speaking to So Foot in France, McCarthy reopened the war of words with a sexist comment, which he had meant in jest.
"I saw so many things in my life and in football for me, it was nothing," he said reflecting on criticism from Brady after his departure.
"Women and football, it's not such a good combination."
Now Gold has waded in and all but ended the row with a brilliant riposte on Twitter.
After a West Ham fan highlighted McCarthy's comments about the co-owner on the social networking site, Gold replied: "More importantly Benni. Footballers and beef burgers don't mix."

Gold's got his tweet-cred back
Proof if ever it was needed that you don't mess with Gold or Brady, particularly after throwing away the chance to make a go of it at their famous football club.
Gold has come in for criticism after a couple of high profile gaffes while using Twitter in recent months.
In the summer he tweeted a picture of Angelo Ogbonna when announcing the signing of Pedro Obiang and just last week retweeted a spoof appeal to find a "missing man" which was in actual fact £7 million summer signing Michail Antonio who has barely featured under Slaven Bilic.
But this latest post is sure to do his tweet-cred the power of good.
