Vincent Kompany says former Manchester City teammate John Stones will prove his doubters wrong this season.
The often-criticised Stones is set for a big role for City this season after Kompany's departure and a serious injury to Aymeric Laporte.
Kompany said: "I've always said John is one of the most talented defenders. He's got such a bright future.
"He's already achieved a lot, let's not forget that. He's not a young defender anymore that hasn't got any experience. He's a multiple Premier League-winning central defender that is growing.
"The one thing I wish for him is consistency - consistency of games and consistency of fitness - and then he will show the world how good he is.
"By the end of it, if City can win a Champions League or something, all of a sudden he'll be mentioned in a completely different category.
"He just has to get himself on the pitch, be himself and he'll be fine. I've not seen signs of weakness I need to be worried about.
"He's just a top-class defender. If now he gets to play games things will sort themselves out, no doubt."
