The 26-year-old Brazilian revealed in a VisitBritain video interview that he was very happy with life in London.
"I am a privileged person to be able to live in one of the best cities in the world and to play for one of the best football clubs in the world too," he said.
"I try to enjoy it and thank God for it every day. Here you have all the entertainment needed for me and my family.
"I know everything here and so does my family: Big Ben, London Eye, Madame Tussauds and Tower Bridge.
"When we first arrived we took our camera and visited those places like any other tourists."
And David's favourite place?
"I like Legoland very much.
"I went with a good friend of mine. It was incredible.
"I cannot remember the very well names of all the things there but it was beautiful. Other parents with kids must visit it."
