Wilshere will block emotion out
But firstly he has to clear his head of all the memories of his time growing up in the place.
He told the Hammers matchday programme for Saturday: “I’ve got to try and block all the emotion out.
“First of all, I’ve got to concentrate on football and I quite fancy our chances. I obviously know them really well.
“They’ve got a new manager, but I know the players, so hopefully it’ll be a good time to play them.
“It’ll be a strange one for me as I was never able to go there and play when I went out on loan as you can play against your parent club, but it’s one I’m looking forward to.
“It’s down to me to show that Arsenal were wrong to get rid of me.”
