The Colombian-born football star was boarding a flight in Moscow when he approached the flight deck.
He told his 102,000 followers on Instagram that he expressed his fears to the pilot as a result of the recent Germanwings tragedy where pilot Andreas Lubitz crashed his jet into the Alps.
Sitting on an aircraft, Asprilla told his followers: 'I went to the pilot's cabin. I strictly forbid the pilot to get out and urinate because if that other lunatic locks the door in, it will happen what happened in that other flight. Everyone knows.
'If he wants to urinate, I have him an empty bottle of water.'
