So yeah, the mighty Google leads me to some facts, some questions and some conclusions:

1) He's not 5'3 ("At least 1.73, according to Benfica fans)
2) He's... ****, to put it bluntly
3) Has Junior actually played more than 2 games for city? Some reports have him playing games for their academy (normally he would be too old, anyway), but a cursory glance at some match reports don't seem to have anyone with a similar name. And he's definitely not been part of their reserves.
4) Does "released by Benfica at 19, having never played for a senior team" and "released by City after 6 months" really scream that "highly rated" to journalists? He's also never played for the Portuguese U21s, but he has 2 caps for the U19s.
5) We seem to be signing Portuguese players (or at least players with Portuguese agents) at the rate of one per year, which seems rather constant to be a coincidence.
That's to make Joao Moutinho feel at home when he joins in a year or two.
