PeakeEa, dude, I know Dozzell's already in your team - it was just to show how he may potentially progress.
Have a look @ Bilal Ould-Chickh (SLB) - might be available on loan but prob. out of budget. Same goes for Kenedy (Chelski)
Lincoln (Gremio - Brazil). Won't come on loan but worth your entire transfer budget if you can prise him away young enough.
Che Nunnely, Abdelhak Nouri, Renato Sanches & Sergio Diaz are amongst the best players I've found =<18yrs. If you've gone past initial transfer window, some or all probably moved on and cost an arm and a leg.
