Riley sent off Everton's Tim Cahill in the Merseyside derby last September
The FA has defended its decision to appoint Mike Riley to referee Sunday's FA Cup semi-final between Everton and Manchester United.
Everton manager David Moyes has questioned the choice of Riley to officiate the match after it was suggested he was a United supporter.
"All our referees are fair, unbiased and objective," said an FA spokesman.
"Mike Riley is one of our top officials and we are 100% confident he will do a good job on Sunday."
Riley was appointed to referee the match at Wembley after original choice Steve Bennett withdrew due to illness.
I think they can be influenced, I think that has been seen in a couple of games I have been involved in recently
But he has upset Moyes with a number of decisions during previous matches involving Everton - notably in 2003 when he awarded a controversial penalty to Manchester United in the final game of the season that cost Everton a place in the Uefa Cup.
"A member of the press asked me if Mike Riley is a Manchester United supporter - I think that is something you would need to bring up with the FA," Moyes told the official Everton website.
"It is something that one or two managers would have something to say about."
At the beginning of the season the FA launched their Respect campaign - part of which was to promote better behaviour towards referees.
