Manchester City are monitoring Dinamo Zagreb winger Antonio Marin.
The 18-year-old starred against City's U19 side when Dinamo visited for the Champions League group game last week - setting up a goal in a 2-2 draw.
He is one of Croatia's most exciting prospects and has also been tracked by Chelsea and Villarreal.
Marin made a breakthrough into the Dinamo first team last season and has made another four appearances this term in HNL1.
The two-time capped Croatia U21 international is contracted at Dinamo until 2024.
While the Dinamo Zagreb U19 side held City's youngsters to a draw, Raheem Sterling and Phil Foden scored the goals in a 2-0 first-team victory for City in Champions League Group C.
