Barcelona midfielder Sergi Busquets says he's always trying to improve.
Busquets believes he is his own biggest critic.
"I am very self-critical - maybe too much. I look at how the game has gone, what I did well, what I did not so well, what I can do better…
"Also, I think [taking care] of the day-to-day things is fundamental. In your social life you have to take care of yourself as well as you can: rest well, train at top form, learn from your team-mates, your manager. I hope to continue improving and maturing and to always be one of the pillars of this Barça."
