The 19-year-old has been granted a work permit and will leave Villarreal for a season in the Premier League.
“I’m very excited about the prospect of playing for Hull City,” he told the club’s official website.
“Hull City is a good club, up and coming, and to have the opportunity to play for them in the Premier League is a great thing.
“I’m sure it will take a little while to get used to being here, but hopefully I will be a success here.
“I think of myself as quite a physical player but I can be graceful too. I like having the ball at my feet and I like running at people.
“I’m still very young and there are a lot of things I still need to find out about myself in terms of playing. Hopefully that will come.
“I’m a huge follower of the English Premier League. Most people think this is the best league in the world and I am no different.
“There are so many great players here. Anybody who is anybody would like to get the chance to play here and experience it.”
