My father, who is now in Heaven, was a supporter of La U, and I think the truth is that a lot of my family would like me to end up there. My dad was the pillar of the family, and sometimes people do things for their family as well.Collection: Dad
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.Collection: Birthday
Football players have always got a problem, some pain, and in some games, I have had small problems with my knee or some pain, and I played anyway, but people don't know if I have a problem or not. People just know if you score a goal or if you play badly, but they never know if you are well or not.
When I am very tired, I know when I have to go in hard or slow down. It helps me to play better in the next match.
Sometimes, when I am not playing in a game, it leaves me feeling very tired when I play in the next one. It is like I haven't trained for a month.
I believe that having a family in the dressing room is very important when it comes to winning trophies.
I played in Spain, and we also had a very good dressing room, and I won a lot of things. So I think that in my experience of being in dressing rooms, it's so important to have a really good group.
Looking at everything I've done in my career as a footballer, at all the titles, I believe that what's hugely important is motivation.
If a footballer is well motivated and has various things to motivate him every day, he will keep achieving his goals.
In my case, my life has changed and improved because different things have motivated me. For example, in the beginning, my motivation was to help my family. Later on, my motivation was to be the best.
As a footballer, everything you've achieved can easily be lost, and then you are nobody. That's just how life is, and that's why you shouldn't let things get you down. That's the reason I treat every match like a final.
I think that if a player wants to be at the very top, he needs to win the Champions League and league titles. That's what makes the great players truly great.
I think it was a good choice to go to Arsenal, the best choice. It has been a positive move, and I love it at Arsenal.
I always want to play and to win because football's my passion; it's my life. That's why, every time we win, I'm really happy.
Since I was a child, I've always been annoyed if I didn't win. If I lost a match, I would be annoyed, and then I would just want to train so that I could win the next day.
Ozil is a quality player, and he really enjoys playing football. I always tell him to enjoy it and not get too worried about scoring.
Neymar is growing and is one of those players who invent things. He always has something more to offer.
Arsene Wenger's style of play is the sort of style the Chilean national team has. Therefore, I am used to it.
I am certainly glad to be the first Chilean ever playing for Arsenal. I will do my best to achieve every possible thing with the club.
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've learnt so much from playing football: I love football, and that's what I do. I enjoy myself, and I'm just trying to be happy.
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.
I like to go to London to eat something or have a drink with my friends. However, I am a very home-loving person, and I spend a lot of time at home.
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 have spent three and a half wonderful years at Arsenal, and I bring with me very positive memories of that great club and its fans.
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.
I think that Manchester United, since I was young - and I'm not just saying this because I'm here; I'm an honest guy, and I never lie - I think it's the biggest club in England. That's what I think.
There are lots of big clubs, and having played for Arsenal, they are also one of them. It's a huge club, and I was there.
Manchester United are a huge club on the global stage. I came here to win everything. Otherwise, I wouldn't have come here.
As a fast player, I want to receive the ball facing the opposition goal, which gives me more vision.
I always said as a kid that I'd like to play for United, and I once spoke to Sir Alex Ferguson about it. We chatted for around 20 minutes, and I told him that my dream was to come here to Manchester United.
