Steve Bruce hit out at a reporter who asked him why he was seen smiling with Ole Gunnar Solskjaer after his Newcastle side lost at Manchester United last weekend.
After the Magpies were beaten 3-1 by Solskjaer's men on Sunday, the two managers were spotted enjoying a laugh together at the full-time whistle while they were walking back to the changing rooms.
Solskjaer and Bruce were team-mates together at Old Trafford but the exchange still angered a number of Newcastle supporters on social media, who accused the boyhood Newcastle fan-turned-manager of not caring enough about the results.
