According to reports in the Sun, the £26 million buy from Valencia crowed about his decision to join Chelsea, saying: " I want to come to England to win trophies- and that's why I accepted Chelsea's offer".
To add insult to injury, the Spaniard mocked: "It was also a question of sporting achievement, not money. Arsenal and Tottenham were both interested in me but they did not compare with the Blues.
Mata also revealed he preferred to play in the blue of Chelsea, rather than the red of Arsenal or white of Tottenham.
He said: "From being a little boy my colour was always blue."
If Chelsea continue to play like they have been playing so far, I don't see them winning anything, they haven't really convinced me yet.
