"It is only natural that if they listen they will progress and I think you are seeing that.
"Now we have to keep our feet on the ground.
"We are picking up newspapers and our players are on the back pages, which is really nice and the players are enjoying it.
"But the minute that you get carried away and the young guys start to believe it then it could be a problem.
