No matter whether it's a futbol or a football -- David Beckham apparently knows his way around it ... impressing the hell out of Peyton Manning with his pigskin skills this week!!!
The two legendary athletes shared a field to shoot a Frito-Lays World Cup advert ... and at one point during a break from filming, the guys got in a little catch.
Manning asked if he'd have to teach DB how to hurl the rock -- but after a throw or two, it became clear to the former Indianapolis Colts quarterback that wouldn't be necessary at all.
