New Chelsea signing Nicolas Jackson pictured in first training session

Nicolas Jackson was photographed during his first Chelsea training session.

Following the addition of several young players in the squad, new Chelsea coach Mauricio Pochettino appears to be working with the youths. 

Nico, as he is affectionately known, is the latest to depart from Villarreal. 

Chelsea has completed the transfer of Senegalese striker Nicholas Jackson from Villarreal for €35 million (£30 million/$38 million).

Chelsea signed the adolescent striker to a long-term contract, and he might spearhead the assault this season. 

Nico Jackson has been named to Chelsea's pre-season squad, which will begin later this week.
