Arsenal loanee Wilshere admits he has sympathy for anyone taking on Republic of Ireland international Arter.
Wilshere said: “You see with a player like Ross Barkley, Harry didn't give him a second.
“He didn't let him turn, he didn't let him do his stuff and I'm sure if you ask Ross he will say they are the worst type of players to play against.
“You hate them. You turn and he is there. You think you have beaten him and he comes back at you. So it is horrible to play against.
“Harry was great. He has been great ever since I have been here.
“He is the one who goes around the pitch, wins the ball back and when he gets the ball he has always got ability with the ball.
“He can dribble with the ball, he can beat players. He is going to be a big player for us this season."
