Former Chelsea striker Tony Cascarino believes Arsene Wenger failed to help Theo Walcott reach his potential at Arsenal.

Walcott, currently on-loan at Southampton from Everton, was 'never coached properly' by Wenger, claims Cascarino.

He said on Talksport: “I have always been a fan on Walcott.

“But I have always felt he has never been coached properly because he was such a young player who left Southampton to go to Arsenal. He joined a fantastic squad of players at Arsenal.

“He sort of found his way. At moments he had one season he had 20 plus goals and it looked like he wanted to play a centre-forward role instead of being a wide player.

“Honestly, I think he's one player who hasn't been coached enough about numerous positions to play in and progression in a player because Theo's got everything.

“He's technically good and he has got incredible speed. I think if you worked with Theo about the tactical side and I think he's an intelligent young man.

“I think one of the biggest things that happened at Arsenal with Wenger was Theo. I didn't think Theo was a player that should have improved like he should have."
