Some are born never to be two-footed.
Some are born with a left foot when their right foot is not even any good for standing on.
Of course you can work on being two-footed but it'll never be natural.
You say you can't understand footballers, even those on £100k a week in the Harlem Globetrotters League (EPL), not being two-footed.
Well there's the proof, it's not possible.
A lucky tiny majority of footballers are born not knowing what their best foot is.
