Anderlecht player-manager Vincent Kompany is backing John Stones to prove his quality at Manchester City.
Stones has started just four Premier League games since February and was criticised for a high-profile blunder during England's Nations League summer defeat by Holland.
"John's such a bright future and he's already achieved a lot, let's not forget that," Kompany said. "He's not a young defender anymore that hasn't got any experience.
"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.
"If City can win a Champions League, all of a sudden he'll mentioned in a completely different category."
Kompany added. "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."
