Wilshere last night urged the club to ensure Walcott signs for the long term.
He said: "Iâ€™ve been trying to work on it [persuading Walcott to sign] all year. Itâ€™s between Theo and the boss. Hopefully, we can sign him up.
"We saw the old Arsenal in patches tonight. It was great. We donâ€™t take any notice of the criticism. We are disappointed about the Bradford result but we had to bounce back tonight.
"Itâ€™s been a tough week for us and we showed great character."
