Mourinho added appointing Taylor for the 17 October match had put "pressure" on the Manchester-based official.

Mourinho has until 31 October to respond to a charge of improper conduct and bringing the game into disrepute.
Taylor issued four yellow cards - all to Manchester United - in the 0-0 draw.
Mourinho foresaw the potential for the FA to take action against him when he spoke before the game, claiming that he "did not really want to say too much more on the matter.
