Simon Kjaer has challenged Milan winger Rafael Leao to "grow enormously" and realise his potential to be one of the top five players in the world.
Leao played a big part in the Rossoneri's first Serie A title triumph in 11 years last season and has been linked with Real Madrid.
The 23-year-old Portugal international, who has just under two years remaining on his contract, scored 14 goals and provided 10 assists across all competitions in the 2021-22 campaign.
Milan defender Kjaer wants to see Leao scale new heights, while he is also expecting big things of 22-year-old midfielder Sandro Tonali and new signing Divock Origi.
"This year I want to see Leao and Tonali: they are no longer kids, they have to grow enormously," the Denmark captain told Sportweek.
"What they did last year is no longer enough. Leao has quality. extraordinary and therefore he can no longer afford games in which one sees little: he must always be decisive.
"If he can make this leap, he can be one of the top five in the world.
"Then I want to see Origi: I was with him in Lille, he was a kid, now I expect a champion who makes the difference because he has everything to be, speed, strength and feet."
Kjaer has returned to action in pre-season after a long lay-off due to a knee injury.
