Jadon Sancho was spotted telling Bruno Fernandes to 'stop moaning' during Manchester United's game with Aston Villa on Sunday.
Fernandes was let frustrated with Sancho in the opening half, but the England man wasn't willing to take any stick from his captain.
Sancho, in a rare start for United, tried to beat Villa man Leander Dendoncker in the final third but was dispossessed by the Belgian.
Fernandes lost his cool with the winger after the ball went out for a throw in, throwing his arms up in the air in anger.
