Chelsea boss Jose Mourinho has been alerted to two top European talents - Lazar Markovic and Pedro Delgado.
According to the Daily Mirror, Mourinho's contacts at Inter Milan have tipped him off about the 16-year-old attacking midfielder Delgado.
The Portuguese playmaker only joined the Italian giants from division two side Portimonense last summer, signing a three-year deal, but Chelsea scouts are now tracking him.
As for Markovic, Mourinho also has contacts at Benfica from his brief stint there and the 19-year-old Serbian international has caught the eye since his move from Partizan Belgrade.
Chelsea are trying to build a strong youth academy to improve the number of home-grown first-team players, and recently won the race to sign 18-year-old Burkina Faso international midfielder Bertrand Traore.
The Stamford Bridge side have won two of the past four FA Youth Cup finals - they've appeared in three of the four - and the likes of Nathaniel Chalobah and Ruben Loftus-Cheek have been earmarked for future first-team action.
Chelsea's graduation rate from youth team to first-team has been identified as an area for improvement, with Ryan Bertrand the most recent successful graduate.
But the Stamford Bridge club hope to reduce the overall average age of their first-team squad immediately - with Oscar, Eden Hazard and Andre Schurrle just three of the more recent recruits to the club under 23-years-old.
And it looks like Mourinho will continue to target highly-rated European starlets for the time being.
