The Hornets confirmed on their official Twitter account and website that the young Portuguese talent had put pen to paper on a four year deal, with the option of an extra year included as a clause for the 19-year-old.

The wonderkid central midfielder has signed a four-year deal with the London club.
The highly-rated youngster has made just six senior appearances for the Hammers in his career with the London outfit.
This is a massive surprise. There were rumours all summer that Quina was likely to leave the club in the window, but for him to go to one of West Ham’s Premier League rivals will be a blow to the club as they probably expected him to go abroad. The 19-year-old has the quality and potential to make a real impact in the Premier League, but he needs to play regularly to improve his game, which is why the loan move to a fellow London club is a bit of a strange move. However, he probably feels like he wouldn’t have been able to get into a team which has been heavily strengthened in this summers transfer window, with midfielders like Jack Wilshere and Carlos Sanchez arriving in his position. Time will tell with this wonderkid, but the Hammers may well regret letting him go in a few years time should Quina reach his enormous potential.
