Mario Pasalic signed for Chelsea in the winter, and, having completed his medical in May, he is set to officially join the Blues on July 1. Although he missed out on a spot in Croatia's final 23-man squad for the 2014 World Cup, his arrival at Stamford Bridge has been seen as a way for the wonderkid to fulfill his full potential.
And now Hajduk could be set to lose another one of their starlets - with Chelsea said to be circling around Lorenco Simic.
Simic, a 17-year-old defender, and captain of Hajduk's junior team, had already passed a trial with Ukrainian side Dnipro Dnipropetrovsk in January, although nothing has come of that move in the following months.
Chelsea's scout Bartosz Oledzki allegedly watched Simic in action during a youth cup victory, in the company of Simic's agent Ivica Piric and lawyer Goran Lucic.
However, any potential deal to capture Simic will wait until July 15 - the players 18th birthday. Although at a younger age securing Simic's signature would be easier, the legal aspects of compensation for Hajduk are made simpler following his path into adulthood.
While Chelsea have received criticism for their youth policy - stockpiling talent, sending it out on loan, and failing to incorporate any youngsters into the first-team - there is no denying that their academy is currently one of the best in the country.
Having been crowned FA Youth Cup and Under-21 Premier League champions in 2014, the Blues have incorporated both homegrown and foreign talent, and Simic, if he was to arrive, would receive training of the highest quality.
