Few will have been more furious with Manchester United's performance against Manchester City on Saturday than club legend Roy Keane.
The Sky pundit was vocal in the aftermath at Old Trafford. "So poor. The difference in class, quality, decision making...everything. It was men v boys. United are so off it it's unbelievable," he said.
While Ole Gunnar Solskjaer lives to see another day, Keane and others have been preaching to the choir about the woes at his former club.
Roy Keane challenges fan
After his TV duties were over, the Cork native was seen outside the Manchester United ground signing autographs for fans. A fan appeared to approach Keane in anger over not signing an autograph for him.
This is how the exchange between the two unfolded:
Fan: You're a legend at this club, you're a legend at this club.
Keane: What am I trying to do? Hang around here all day and sign autographs? I've signed autographs.
Fan: You don't have to be like that though.
Keane: Like what?
Fan: Why are you being like that?
Keane: Be like what? What did I do?
Fan: You're an absolute prick.
Keane: What did I do? You've had a few drinks and they've got beaten and you're taking it out on me? Alright, you've had a few drinks, what's that got to do with me? You've had a few drinks, you can tell. What have you had, two pints?
Keane: I've signed for this guy and I've been polite. Tell all your mates you give lectures.
Signing autographs and taking photos for fans is a thankless job at the best of times and something the former United captain has probably done in his thousands in the past.
