Chelsea manager Jose Mourinho reportedly shoved a teenage boy after he caught the youngster filming him while walking along a street in West London.
Fourteen-year-old schoolboy Otto Nahmmacher, who is said to be a Chelsea fan, spotted Mourinho walking in Knightsbridge the day after his team's 2-0 win over Aston Villa.
The clip, which has been published by The Sun, shows Mourinho talking on his phone before appearing to shove the boy once he noticed that the youngster was filming.
Otto's father Hans told the newspaper that the Portuguese coach is "losing the plot".
Mourinho was recently fined £50,000 by the Football Association and given a suspended one-match stadium ban after criticising referees in a seven-minute TV rant.
