Moyes reserved special praise for the goal of the game from Mirallas, who struck early in the second half to hand the visitors the lead.
"We saw one last week, these special goals and they are the sort of goals you see Gareth Bale scoring.
"Now Kevin has one last week and one this week. It was great, good close control, running at speed and a fine finish. It's the type of goal that supporters want to see."
