Moyes is excited at the progress made by Coleman.
"He is pushing all the time to get in the team," said Moyes, who could include the exciting Ross Barkley, 16, on the substitutes' bench for the first time today against Manchester United. "He is on the verge of it. He is a right-back but he came on against Aston Villa in midfield in the last game because we know he is capable of getting forward.
"We're short of a right-sided player. We have been looking for a solution and Seamus could be one."
