The Argentine has won four successive Ballon d'Or awards, but believes he can become an even better player as he strives to win everything with Barcelona and Argentina
Messi collected his fourth consecutive Ballon d'Or earlier in January, and has been at the heart of the record-breaking Barcelona team as they moved clear at the top of La Liga in the first half of the season.
However, Messi insists that the game is not about collecting records, and his aim is to win everything he can for both club and country.
"It is not my objective to break records, I want to win every season everything possible with my team, be it Barcelona or the national side," Messi told Argentine newspaper Clarin.
"We all live trying to improve in every area of life and football, and I am no different."
Messi also says he thinks Barcelona could get better, but believes there was little difference working under Tito Vilanova compared to Pep Guardiola.
"Of course we [Barcelona] can improve, we will never be perfect, but I will leave that to Tito Vilanova, our coach," he added.
"There is very little difference [between Guardiola and Vilanova], they both enjoy playing a good possession game, and each have their own personality."
