Chelsea manager Jose Mourinho has suggested that Chris Foy should not referee any more of the Blues' matches.

• Mourinho questions Foy
Foy was in charge at Villa Park on Saturday as Chelsea suffered a shock 1-0 loss courtesy of Fabian Delph's goal in the second half.
But the match was marred by two red cards, as Willian received two bookings and Ramires was also dismissed after a strong challenge on Karim El Ahmadi.
Mourinho was also sent to the stands in the final minutes after he came on to the pitch as players confronted one another following Ramires' tackle.
Speaking after the loss, Mourinho said: "Maybe it's helpful that the [Premier League referees'] committee doesn't send him [Foy] to our matches.
"I don't have the right to request [that]. It's just I think they have to analyse the situation and see if every time he has Chelsea -- or not every time -- but many times he has Chelsea and problems are there, I think maybe it would be a good decision."
Although he was not manager then, Mourinho recalled Chelsea's defeat to QPR in 2011 when Foy dismissed Jose Bosingwa and Didier Drogba.
"The last time I remember something similar was in a match at QPR's stadium," Mourinho said.
When informed that it was Foy who took charge of that match, Mourinho said: "I didn't know [that]. It's a coincidence."
Mourinho revealed the fact that Foy was to officiate the game had been regularly discussed at Cobham ever since the officials were announced. "The players were speaking about it during the week,” Mourinho added. "They have a reason.
"I never care who the ref is. I don't want to know. But during the week the players were speaking about the situation and I think from now on the next time we have Mr Foy I have to work my people in a different way."
If the Football Association decides Mourinho or anyone else who entered the pitch has broken Rule E3, which states managers must not leave their technical area, it can fine him 8,000-12,000 pounds.
If anyone involved is found to have used abusive or insulting language he can be hit with a two-match touchline ban.
