Liverpool, Chelsea and Newcastle have joined Manchester City in the race for Hajduk Split's highly rated centre back Luka Vuskovic.
The Premier League sides were among those to watch the 16-year-old defender in the UEFA Youth League at the Stade de Geneve in Switzerland on Friday.
The 6ft 5ins centre back, who has already broken into Split's first team, helped the club's U19s progress to the final of the UEFA Youth League in a 3-1 win over AC Milan on Friday.
Manchester City have already made an enquiry for Vuskovic, who is valued at around £12million, while Liverpool, Chelsea and Newcastle were represented in Geneva.
