Wilshere last night urged the club to ensure Walcott signs for the long term.
He said: "I’ve been trying to work on it [persuading Walcott to sign] all year. It’s between Theo and the boss. Hopefully, we can sign him up.
"We saw the old Arsenal in patches tonight. It was great. We don’t take any notice of the criticism. We are disappointed about the Bradford result but we had to bounce back tonight.
"It’s been a tough week for us and we showed great character."
