A young Brazilian guy (twitter @gabrielfuh_) who watches the São Paulo youth competitions has been kind enough to explain what happened with Lucas Evangelista.
Apparently, Evangelista was playing in a youth tournament in Holland and ended up training with either PSV or Ajax- this annoyed Twente who decided to break off their agreement with Desportivo Brasil so they can't loan to them anymore which complicates getting a work permit given that Lucas is not a Brazilian youth international so is unlikely to qualify as an exceptional talent. So now he has gone to São Paulo with an option to buy, along with Gladstony who is no longer on Desportivo's books.
I asked him how this will impact Bruno Gomes, and if he is likely to qualify for a work permit. He claims that it will depend a lot on whether he gets selected for the Brazilian u-17 for the World Cup and South American championships.
Gomes is breaking all sorts of records in São Paulo youth leagues and cups and is carrying the form over to u-20s even though he is just 16- Scoring 3 goals in 4 games- he got a goal and an assist today so there is a decent chance- but it's Brazil I guess it will be competitive as hell for Striking places.
