#2 Vinicius Jr (Real Madrid)
Age: 18
Position: Striker
In Vinicius Junior, will Los Blancos be landing the next Neymar or the next Keirrison? It is not always easy to guess how even the most talented youngsters will step up when swapping Brazil's Serie A for the hustle and bustle of European football.
Vinicius Junior is the newest name in a long line of brilliant Brazilians and last month was unveiled amid much fanfare by Real Madrid – just eight days after his 18th birthday.
For the former Flamengo wonderkid, it was the next step in his fast-track to the top. And he has had time to prepare, having made only a handful of appearances with the Rio de Janeiro club before agreeing an astonishing €45 million (£38m/$50m) switch to the Champions League winners.
