Roy Keane has referred to recent pitch invaders as "idiots, scumbags and a disgrace" after Aston Villa's Robin Olsen was attacked at the Etihad.
Manchester City won the Premier League title in dramatic style as they scored three goals in five second-half minutes. Supporters ran on to the pitch when the full-time whistle went and the Villa goalkeeper was targeted by a fan. It is an alarming trend that has been under the spotlight in recent weeks.
Patrick Vieira was attacked by a fan during the week at Goodison Park after his Crystal Palace side were beaten by Everton. Players were also targeted during play-off games at Nottingham Forest and Port Vale this week. Keane has questioned how far some fans may go as they pursue players and managers.
