Academy youngster Dylan Crowe is reportedly a target of Manchester United, Brighton, RB Leipzig, Borussia Mönchengladbach and Benfica.
According to Goal.com, the clubs are all eyeing the 17-year-old right-back, who has won nine caps for the England U17s, and are said to be willing to pay the Blues up to £500,000.
Second-year scholar Crowe, who broke into the U23s side at Portman Road last season, is yet to sign a contract with Town, despite having turned 17 - when players are permitted to sign their first professional deals - in April.
The Blues recently lost 16-year-old Ben Knight to Manchester City for a fee of just over £1 million, while academy schoolboy Marcelo Flores, whose father Ruben is a coach at Playford Road, is interesting Arsenal.
Chelsea, Liverpool and Barcelona are also among the clubs believed to have been tracking the Canadian.
