2. Sergi Roberto | FC Barcelona
After three seasons of threatening to break into the first team at Barcelona, Sergi Roberto has finally made the breakthrough this term.
The 21-year-old midfielder has made 15 appearances in all competitions under Tata Martino - and has looked comfortable amongst the multitude of superstars at the Camp Nou, which is no surprise considering he learned his trade at the club's famed La Masia academy.
Roberto will need to wait a little longer before becoming a first-team starter but, for the time being, he's certainly proven himself to be a very handy back-up option.
