Brian Clough joke

Sir Bobby Robson is queueing outside the Pearly Gates, waiting with the other recently deceased to be let in to Heaven, when he is surprised to see a familiar figure with dark wavy hair and a sheepskin coat approaching Saint Peter.
"Look, young man," says the man loudly (and in a slightly nasal voice) to Saint Peter, "You need to change your attitude and work harder, or you're off the team. All right?"
Saint Peter says something quietly and deferentially to the man, who then strides off.
When Sir Bobby gets to the front of the line, he asks Saint Peter, "Wasn't that Brian Clough telling you off?"
"Oh no," Peter replies, "that was God, he just thinks he's Brian Clough."
