When he pushed his head into the face of Hull City midfielder David Meyler on Saturday, it was not only shocking and violent, it was ludicrous. A 52-year-old man squaring up to someone almost 30 years his junior. If it had happened in a pub, people would have laughed at him. Because it happened on the edge of a football pitch, there is outrage mixed with disbelief. His behaviour, though, betrays an inability to grow old gracefully and he risks undermining everything he has achieved because of it.
