“Barrie is such a talented player and you know what I think of him and how good a career he can have ahead of him.
“But he has had a lot of games with Rangers, been away with Scotland and these couple of weeks have helped him to recharge the batteries.
“It’s a challenge for a young, attacking player like Barrie for his defensive responsibilities and when the ball breaks down where does he need to be and what areas he needs to fill.
“It’s making sure if a player does that they understand the role they need to fill.
“I’m delighted for him to see him that way, and credit to him for working hard and I think he will have a very big career ahead of him.
“He has a great work ethic and great commitment and he took that into the game on Saturday.”
