Jose Mourinho reportedly shoved a young fan who was filming the Chelsea manager on his phone as he walked past him in the street.
Blues supporter Otto Nahmmacher spotted Mourinho in Knightsbridge on Sunday and quickly whipped out his phone to take a video.
But when Mourinho approaches, he apparently pushes the 14-year-old, almost causing him to drop his phone.
Nahmmacher’s dad, Hans, told the Sun: ‘He (Mourinho) is losing the plot’.
Mourinho is under increasing pressure following Chelsea’s poor start to the season which continued with a dull 0-0 draw away to Dynamo Kiev on Tuesday.
