Former Tottenham defender Jon Woodgate has declared John Stones the best centre-half in the country this season.
Stones has rediscovered his best form for Manchester City in recent months.
Woodgate told the Daily Mail: "For me, John Stones is the best centre-half in the Premier League at the moment.
"Him and Dias are like having two Rolls Royces in the garage at Manchester City.
"He's an outstanding centre-back, he could play in the Real Madrid team, Barcelona. No doubt about it because he is that good.
"He is unbelievable on the ball, can defend, head it, quick. I think he has to be in the England team, the first centre-half. He's a similar stature to myself but I think better. Everyone will have their own opinion."
