Alan Pardew made the headlines for all the wrong reasons yesterday afternoon when he aimed a headbutt at Hull City midfielder David Meyler.
The 52-year-old, of course, is not the first manager to have let his temper get the better of him. Below, Sports Mole has looked back on five other incidents that have seen coaches become involved in physical altercations.
1. Brian Clough, 1989
As Nottingham Forest supporters poured on to the City Ground pitch to celebrate the 5-2 win over Queens Park Rangers with the players, manager Brian Clough was disgusted by their actions. However, rather than return to the dressing room, Clough decided to show his displeasure by aiming punches at random fans. Such was the high esteem that Clough was held in that two of the men whom he had hit later said sorry to him on national television.
Clough also punched Roy Keane during the midfielder's time at Forest. Of that incident, he once said: "I only ever hit Roy the once. He got up, so I couldn't have hit him very hard."
2. Jose Mourinho, 2011
As players from Real Madrid and Barcelona scuffled near the touchline, coaching staff from the two teams also became involved. All of a sudden, Madrid boss Mourinho appeared from nowhere and proceeded to inexplicably jab his finger into the eye of Pep Guardiola's assistant boss Tito Vilanova. Unsurprisingly, Mourinho received a suspension and a host of negative headlines in Spain.
3. Delio Rossi, 2012
Whatever Fiorentina playmaker Adem Ljajic said to his manager Rossi as he was substituted, it certainly caused some anger. As Ljajic took his place on the bench, Rossi bundled in after the Serbian and proceeded to grapple with him. Ultimately, Rossi's antics cost him his job.
4. Jorge Jesus, 2013
When managers turn physical, it is often against players or supporters, but Benfica coach Jorge Jesus decided to take on the police. As the authorities attempted to stop fans from entering the pitch after Benfica had beaten Guimaeres, Jesus took exception to the treatment of one man in particular. Instead of turning a blind eye, Jesus pushed officers out of the way in an attempt to free the invader, which earned him a 30-day suspension.
5. Nelson Vivas, 2013
The Argentine struggled to make a name for himself in England with Arsenal during his playing career, but having ventured into management back in his homeland, the 44-year-old landed himself in hot water. After his Quilmes side had drawn 1-1 with Atletico Rafaela, Vivas laid into a fan who had been critical of the performance, before he was dragged away by police. Later that day, he was relieved of his duties.
