Walcott opened himself up for criticism when he admitted diving in an attempt to win a penalty against Leeds, before then being pulled back as the referee did point to the spot, which captain Cesc Fabregas converted.
The 21-year-old, however, insisted: "I have got no regrets about what I said.
"I am an honest player, I want to be honest with my team-mates, Leeds and the manager and all the staff.
"If I am going to be punished for being honest then I can't win."
Walcott added: "People say that if you get the slightest touch you should go down and when you do go down they have a go at you for going down, so you can't win.
"But I am not bothered. If the referee's going to punish me or any other players, then I can't do anything about that."
