Scotland women's coach Gary Parker believes England's professionalism sets them apart from the rest of the RBS 6 Nations sides.
England have scored 72 unanswered points in their opening two games against Wales and Italy respectively and have Ireland in their sights next week.
But there are no sour grapes on the side of Parker who has nothing but respect for an England side who play a fast flowing game.
He said: “England have worked very hard to get to the position they are in at the moment and they deserve all the success they are having.
“They have a great set-up and they work on the right things like handling and fitness which is the right way to go about things.
“They are leagues ahead of anyone else but they are the standard and all the other nations will have to work even harder to be up there with them.”
