But he's not hanging up his boots just yet. Like every hero, Becks is out for one last job before he returns to plunge some wealth back into MLS as an investor.
Where should David play out this final act in his on-field career? Digital Spy rounds up some of the possible destinations before inviting you to share your thoughts.
In a Rangers-less SPL, Beckham will arguably get plenty of time on the ball at Scotland's top club to pick out pinpoint passes to his teammates, as well as the chance to add to his sole Champions League medal. Whether he'll take to the shift in temperature from LA to Glasgow is another matter...
New York Cosmos
Read that statement again carefully. D-Beck hasn't definitively said that he'll leave the US. His fellow Manchester United legend Eric Cantona has been installed as Director of Soccer over on the East Coast.
This way, David still gets to stay with his American kids all year round, Victoria keeps her fashion connections, and two '90s superstars get to rekindle their wonderful relationship. Joining the North American Soccer League will be a step down from MLS, but when your honorary president is Pelé, that doesn't really matter.
David, of course, is only one half of a greater whole. Yin and Yang, Morecambe and Wise, peanut butter and jelly, Nelly and his plaster... Posh and Becks! We can't think of a city that would suit fashion queen Victoria more than Paris.
Since the Qatar Investment Authority's takeover of the club, they've got plenty of oily money sloshing about to make sure that Becks will be kept in Calvins and bling for his final playing hurrah.
David's people have already ruled out a move to Australia, but that was before he confirmed his departure from the Galaxy, and we all know that agents' pronouncements should be taken with a heft of salt.
So why Sydney? Well, having got used to sunny LA, a jaunt to Oz certainly won't have Becks popping on a snood and gloves. The club is also sponsored by Beckham's favoured sports brand Adidas. Better still, if he and Vic conceive a child in the dressing room, in "Sydney" they've got a perfectly acceptable name to run with for a boy or a girl!
He might have attended Tottenham Hotspur's school of excellence, and it was an FA Cup defeat to the Gunners where Beckham's United career started to unravel - Lord Alex of Ferguson allegedly chucking a boot at him in the aftermath. But since then he's been on good terms with North London's finest.
In 2008, Becks trained with Arsenal for three weeks and was snapped in the club's tracksuits sparking speculation that he may join them for a little while. People might think that Beckham is too old and slow for the top flight, but he's unarguably more mobile than the poor chaps in the Gooner treatment room. His son is a fan, plus, we've got a fashion week here and everything.
Preston North End
If a move back to England is on the cards though, there really is only one place Beckham should end up. Not United, who don't really need him despite the presence of evergreens Paul Scholes and Ryan Giggs, but Preston North End.
Beckham made five glorious appearances at the club in 1995 on loan, banging in two goals. That's a goals-to-games ratio he's not bettered anywhere since. One of them was a screamer direct from a corner (a feat he repeated against the Chicago Fire last year). Short of a trip back to Brimsdown Rovers, this would be the best way for Beckham to have the ultimate hero's return.
