It is not just improving as a footballer that interests Mata, who is also studying for two university degrees, one in sports science and the other in physical education and marketing.
"I just try to do things that normal people my age do," said Mata, who will continue his education from a distance.
He added through a translator: "I'm very much enjoying my life in London right now. It's an incredible place.
"I am going to English classes and I think all of this represents a wonderful opportunity to grow as a person and experience a new culture."
