Cruz Beckham knows he has to start working on his ball skills early if he wants to be like dad David Beckham when he grows up.

Posh's youngest son was spotted showing off his fancy foot work with brother Romeo during what looked like a serious match on a playground in Beverly Hills.

Cruz - who turns four today - wore an L.A. Galaxy shirt with the number 23 on the back, just like his famous dad's.

Beckham's boys looked adorable during their playground kickabout - but we think Cruz may have committed a fairly serious foul on big brother Romeo during one particularly enthusiastic tackle.

That's gotta be worth a yellow card...
