"Players sometimes need to feel important and loved by the club."
"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 don't care if I play on the wing or in the middle. There is no difference."
"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 never regret my decisions."
"I'm a professional, so any match against Barcelona in the Champions League is special to me."
"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."
"I can't be happy with drawing or losing a match. It actually makes me really sad when that happens."
"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."
"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."
"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."
"I always give my 100 per cent."
"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."
"Arsenal plays very well, which fits my style. That's why I moved here."
"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."
