Arsenal pair Carl Jenkinson and Kieran Gibbs were spotted wearing First Capital Connect uniforms at a London train station this week.
The explanation as to why the pair were spending an afternoon on the London rail network has so far been kept under wraps by Arsenal.
Jenkinson spent this week with the England Under-21 side, while Gibbs joined up with the senior team, but did not play any role in either World Cup qualifier against Montenegro and Poland.
Arsenal posted a photo of the pair working the railway on their official Twitter page.
