That reliable site of Wikipedia has him down as being a Liverpool supporter though there is an article floating about from the Mail (make of that what you will) that he is quoted as saying "Bayern Munich are the best club in the world". Basically he has the choice of every single team in Europe and hopefully it won't be a case of 'money talks' because he isn't exactly going to be skint at any of the top European clubs so hopefully it's more a case of picking the best club to develop with. Arguably that would be Ajax but his Dad may decide that moving to Germany/Spain/England/Italy is better for him.
Personally I think he will end up in Spain or Germany as his Dad is an ex footballer and a current coach and will know that both those leagues are top quality but don't come with the ridiculous media attention that England does.
Also I suspect his Dad will have a big say in it as he is only 16 so I'm guessing that he has to have parental / guardian supervision until 18 if he wants to work abroad.
