The former Premier League boss also believes that Walcott isn't good enough to play as a centre forward.
The debate about whether Walcott can cut it as a centre forward is one that has gone on for quite some time, with the player himself making it clear that is where he would prefer to play.
As of yet though, he is yet to be properly used in the position, with Olivier Giroud being preferred in the role ahead of him, while they are also consistently linked with a move for a top centre forward in Europe, such as Karim Benzema.
Souness though, says Wenger clearly does not trust the player in the position.
“The manager doesn’t trust him there,” Souness told Super Sunday.
“He’s not trusting him in that position because he’s seen it in training, he’s seen it in the games he’s played and he doesn’t trust him through the middle. He sees him everyday in training and when he’s introduced him as a centre forward and he’s not liking him there.”
Not good enough to be a number 9
The former Premier League manager also personally believes that Walcott is not good enough to play as a first choice number nine for Arsene Wenger’s side.
Because of his pace, Walcott has spent the vast majority of his career playing as a winger, with his speed a constant threat to the opposition defenders. However on the rare occasion he has been employed up front, he has failed to impress.
And Souness says he believes that the player doesn’t have the intelligence to play as a centre forward meaning Arsenal cannot rely on him as their new striker.
“I don’t think long term he’s a centre forward for Arsenal through the middle,” he added.
“I think he can come on in certain games and be a real influence there, but I don’t think he’s got the cuteness, or he’s clever enough to be a number nine. He’s a real threat through the middle in certain games but if you hang your hat on him as your new centre forward then it isn’t going to happen.”
