David Sullivan and David Gold completed their takeover of West Ham on January 19, 2010.
The Hammers-supporting duo sold Birmingham earlier in the 2009-10 season and took over from the Icelandic consortium that had purchased the club in 2006 before running into financial problems associated with the global crash.
The pair, who previously held a smaller stake in West Ham, acquired 50 per cent of the club in a deal which valued it at £105million and became joint chairman, with Karren Brady becoming vice-chairman.
Sullivan said: “We’ve got the club that we’ve always wanted. We are West Ham fans and I don’t think we would have bought West Ham if we hadn’t been fans as, from a business point of view, it is in a serious mess.
“The club is now back in the hands of East Enders, people who understand the community and its passion for the Hammers. I believe that depth of feeling will also bring us through what has been a difficult period.”
Sullivan set long-term goals of moving from Upton Park to the Olympic stadium – which was achieved in 2016 – and securing Champions League football within seven years.
The short-term priority of securing Premier League survival was achieved but West Ham were relegated the following season, bouncing back at the first time of asking.
The Hammers have stayed in the top flight ever since, with their best campaign yielding a seventh-placed finish in 2015-16.
Gold and Sullivan subsequently increased their stake in the club and remain in charge.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
