Speaking through an interpreter, the new St Mary's chief said: "I know the Premier League really well. In Spain we follow it closely and I am a great admirer of English football. I am very happy to be here.
"I am very passionate about the Premier League. I have seen many games and it is a very attractive league to me.
"I have spoken at length with people that know this league and have been part of it, such as Jose Mourinho, who is a good friend of mine.
"He told me the best football in the world is being played here. That has fully convinced me to come here."
