"It is alleged that the manager used abusive and/or insulting language towards a match official during the 81st minute.

"Dean Smith has until Tuesday [26/01/21] to respond to the charge."

The Villa boss was furious Manchester City midfielder Rodri appeared to run back from an offside position when he dispossessed Tyrone Mings to set up Silva for the breakthrough goal.

Smith revealed, amid his anger on the touchline, he was shown a yellow card by Moss for asking fourth official David Coote "if he got juggling balls for Christmas".

This was swiftly followed by a red card for something else said by the Villa boss.

Smith said: "It wasn't swear words. He (Moss) came over and said he was interpreting the laws of the game. I said, 'Well you should have done that earlier in the game'.

"I think I got treated rather unfairly. I've heard a lot of worse things said to Jonathan Moss before and he's not dealt with it like that. It looks like he couldn't wait to give me a yellow and then a red."
