Jese Rodriguez | Real Madrid
The 20-year-old broke the record for most goals in a single season with Castilla last term and he's expected to make the jump to the senior Real Madrid team sooner rather than later. If not, they'll be plenty of clubs queing up to take him.
Oliver Torres | Atletico Madrid
Torres shot to prominence with the European Championship under-19 winning Spain team last season. The gifted attacking midfielder has stepped up with his age group and even made an appearance for the Spain under-21s. He's also appeared for the Atletico Madrid first-team last season while just 17.
Gerard Deulofeu | Barcelona
The next great hope from La Masia. Deulofeu has had clubs sniffing around for the past 12 months, but he's yet to make an impact on the Barcelona first-team. Expect that to change next season.
Denis Suarez | Manchester City
The 19-year-old former-Celta Vigo teenager was wanted by Manchester United, Chelsea and Barcelona - but City won the race. He's been cutting apart reserve team defences ever since, he needs competitive first-team experience.
Suso | Liverpool
Suso made his first-team debut last season, and briefly broke into the side on a permanent basis. Brendan Rodgers clearly rates him highly, and he should be great to watch alongside Torres & Suarez (not THOSE two, the Spanish duo).
