Manchester United midfielder Paul Pogba was left fuming with his team-mate and captain Harry Maguire after the England man accidentally kicked him the head, drawing blood from the Frenchman.
United beat relegation-bound Norwich 3-2 at Old Trafford to keep them in the hunt for the top four and Champions League football.
Having led 2-0, United were however pegged back by Norwich and the tension in the ground was palpable.
It appears that tension translated itself onto the players, with Pogba appearing angry with his captain after Maguire had struck him in the head accidentally when jumping for the ball at a corner.
