Aberdeen manager Mark McGhee praised Charlie Mulgrew after his majestic free-kick gave the Dons a 1-0 victory over St Mirren.

Mulgrew stepped up in the closing minutes at Pittodrie to curl in a fine 20-yard effort after John Potter had fouled Darren Mackie and McGhee was full of praise for his defender.

He said: "We have a trump card at the moment with Charlie as his left foot is a wand. Any free-kick around the box is like a penalty for us.

"I don't know about anyone else but when we were awarded it I sat down as I thought the most likely outcome was that it would be in the back of the net and I think we are lucky to have that."

The Pittodrie boss believes the former Celtic and Dundee United man is also working hard on his defensive duties.

He said: "I think Charlie has the ability to become a good defender and is developing the mentality that he can be a good defender. "He has stopped hearing people say that Charlie Mulgrew can't defend. Sometimes if you keep hearing that you start believing it."
