Arsenal hero Martin Keown has taken a swipe at Theo Walcott.

Keown reckons Walcott should tread carefully when it comes to negotiating a new deal - because he hasn't really done all that much to impress at The Emirates.

Speaking to talkSPORT, he said: "He hasn't really cemented himself [in the team] yet, and I think it's ten years he's been at the football club.

"You couldn't really call him first choice."
