Howard was signed by Moyes for Everton.
He said: "David Moyes has come in for a lot of criticism but the one thing I will say is that he’s never kicked a ball for Manchester United. As players you have to stand up and be counted.
"It’s a very easy thing to talk about the manager and unfortunately that’s the pressure of it.
"But those players won the title last year and are a damn good side."
