Wilshere reckons the fact he along with Kieran Gibbs, 23, Aaron Ramsey, 22 on Boxing Day, Carl Jenkinson, 20, and teenager Alex Oxlade-Chamberlain all penned new deals will spur Walcott to re-signing.
He said: “I think Theo looked at that.
“We’re all great friends, the British boys. We all go out together, have meals together and we all sit together when we’re on the road.
“It was nice to sign a new contract. It’s a great club. It’s like home, my friends and family are down the road. I’ve shown commitment to the club and they’ve shown commitment to me. We have a good thing going on.”
