Chelsea manager Jose Mourinho has been fined £8,000 and warned about his future conduct after being sent off in last month’s 1-0 defeat by Aston Villa.

Mourinho walked on to the Villa Park pitch to speak to referee Chris Foy after Chelsea’s Ramires was dismissed.

He denied an improper conduct charge but it was proven at a personal hearing with an independent regulatory commission on Wednesday.

“I don’t know why I was sent off,” Mourinho said after the match.

“I asked, but the referee refused to speak to me.”

Mourinho was critical of Foy  after the game at Villa Park as Chelsea’s lead at the top of the Premier League was reduced to four points.

Ramires was shown a straight red card for a two-footed tackle on Villa’s Karim El Ahmadi, an incident that sparked a touchline fracas.

Mourinho claimed he was trying to speak to Foy because Ramires was pushed by Villa striker Gabriel Agbonlahor, who had been substituted.
