It's a rivalry that's been brewing for over two decades, with a bitter business breakup at its core. Yesterday's clash between Brighton and Brentford at the Gtech Stadium saw the Seagulls' owner, Tony Bloom, take a seat in the away end, rather than join his fellow big cheeses in the executive box. And it's all because he's not exactly on speaking terms with his Bees counterpart, Matthew Benham.

Their feud dates back to 2004, when Benham left his job at Premier Bet, Bloom's company, to start his own betting empire, Smartodds. The split was messy, with Bloom taking Benham to court over the terms of their parting. A settlement was eventually reached, but the damage was done.

According to insiders, Bloom's beef with Benham isn't about the fact that he became a rival businessman – it's about the way he did it. "Tony's all about loyalty and generosity," a source spills. "He's a big-hearted guy, but he expects the same in return. Benham's success on Saturday, with Brentford thrashing Brighton 4-2, only adds fuel to the fire."

It's clear that this is a rivalry that's far from over. And with Bloom and Benham still at odds, you can bet your house that this isn't the last we've seen of these two.
