The forward has failed to impress again this season.
The winger has been given his chance to impress in a central role this season, having long desired to move into a central position.
He had looked comfortable in the role earlier in the campaign, but has failed to impress with just eight goals in all competitions to his name this season.
Recent weeks have seen him replaced in the starting line up by youngster Alex Iwobi leading to some suggesting his time with the club may be coming to an end.
Keown though, doesn’t believe that Walcott will ever leave while Arsene Wenger is in charge.
“To me, Walcott underlines Arsenal’s season more than any other player – inconsistent,” he told the Daily Mail.
“Has he missed a massive opportunity to cement his place in that team? He has had to stay very strong mentally.”
“He’s been at the club for 10 years now and I think he’s at a crossroads, but Arsene Wenger certainly believes in him. While Wenger is at the club, Walcott will be there.”
There is no denying that Walcott has failed to kick on during his time at the club, having looked an exciting talent when a youngster at Southampton.
Much of that has been to do with injuries, with several long-term absences having hated his progression considerably over the years.
He still has much to offer though, and should the Gunners decide to sell there would likely be a long line of potential suitors.
