Barcelona striker David Villa says he has improved as a player since joining the Catalan club, paying special tribute to Lionel Messi.
The Spain international joined Barcelona from Valencia in the summer of 2010 for €40 million (£35m) after spending five years at Mestalla.
Villa enjoyed immediate success at Barca, helping the club win the Spanish Supercopa, La Liga and the Champions League in his first season at Camp Nou.
The 29-year-old has been used in a wider role at Barca, rather than being a target man, and he claims he has become a better player since his transfer last year.
