I always wanted to be a footballer; I always wanted to play. I was born to be a footballer.
I want to win the Premier League and the Champions League.
Playing with Neymar gives me happiness and confidence.
Arsene Wenger's style of play is the sort of style the Chilean national team has. Therefore, I am used to it.
It wasn't easy to leave Barcelona. I fulfilled a dream when I moved there - to play in Spain and for the champions - but very few players stay in the same club all their life. To leave is normal.
I think football saves many people. It can give you a life of luxury, but people don't see all the effort that goes in behind the scenes. That might mean not seeing your family or missing your mother's birthday; many players are so focused that they miss the birth of their children.
I've learnt so much over time and with the experience that I've gained. You can't please everyone.
I do explore the city if I have the time for it, but normally, I would rather stay relaxed at home. London can be a stressful place because it's crowded and it's a big city.
You play one game after another, meet new people every day, and travel a lot. That is why I try to disconnect and relax as soon as I get some time off.
I am very proud to be the first Chilean player ever to play for United's first team, and I hope I can show our fans all around the world why the club wanted to bring me here.
