Arsenal hero Lee Dixon is backing Manchester City defender John Stones to improve even further.
Stones was left on the bench for Manchester City's Premier League clash with his former club Everton in midweek.
Dixon said: "I think there's more to come from him. I've really been a big fan of his for a long time.
"He went through that rough spell and he talks about (seeing a) sports psychologist, and why wouldn't you?
"If you're a young player in this game now, at any standard, you train your muscles, you train your physicality. Why not train your brain as well, to think in a different way.
"I think he's always been positionally very good. He's always read the game really well. He just got caught up in his own talent.
"Because he was so talented on the ball, he was encouraged to play out a little bit and once he got into mistakes, he didn't know how to get out of those.
"I think the fact he's worked on his mind and how he thinks about the game has simplified it and we're seeing him now in a great position, intercepting balls and being the player he was before - but he's just matured a little bit.
"I honestly think he will go on and on and on, and get better and better."
