When I was a kid, I used to love playing football so much that I genuinely wouldn't be able to fall asleep at night.

Whatever the circumstances, playing alongside the best in the world is something I can tell my kids about.

Football without critics wouldn't be football.

The only way I can show the doubters is on the field. Not for them, but for my team-mates, who are with me every day. We work to get good results.

I know Barca have their own style and DNA but I think I can play here.

A good financial proposal doesn't mean you'll get to do a lot of things. There are times when you have to think about your career.

Coutinho is a great player, he will help Barcelona to reach their goals.

If I had left football I would not have had anything.

My first steps in football came thanks to my big brother who taught me the game.

At Tottenham, I enjoyed the first year but the second was tough.

At Corinthians, I had the pleasure to play with Ronaldo who also taught me a lot.

I don't play for the critics, I play for my team-mates.

People always talk and always will - 'He's good now because he's at Barca,' 'He was only good then because he was in China,' blah, blah, blah. When I was at Bragantino and I went to Corinthians it was the same; it was the same at Tottenham and in China. I've had that since the beginning.

In 2011, when I was in Corinthians, I received an offer from Russia that offered me to win 10 times more than in Brazil and I answered: 'What I can do with five, I can do with two.'

A player can make money at any team he goes to. The important thing for me is to be happy with the decision that I am making.

Money for me never came first.

I've had the opportunity to play with Neymar on the national team. Now I'm playing alongside Messi. He's a different player, but he's the best player in the world.

When someone is playing alongside the best player in the world, you just have to do what you need to do to make him the best and ensure that the ball gets to him as quickly and as often as possible.

Messi has helped me a lot.

You have to face challenges with courage.

In England, I have acquired more tactical knowledge and improved the speed of my decision making.

Barca are Barca and I don't think you can say no to them. To play here is to realise a dream.

I was getting ready to take a free-kick in a game between Brazil and Argentina. Suddenly, I saw Messi behind me getting closer bit by bit, and he says 'are we going to Barcelona or not?' I said, 'if you want to bring me there, you can. I'll go.'

I hope to build a beautiful story here with Spurs like I did with Corinthians.

It's a great pleasure to be linked to such a great club like Tottenham.

I feel I am ready to experience football at the highest level in Europe and the opportunity to play in England is a dream.

Playing alongside Messi is special for me. He's a player I always wanted to play with. I have played against him with Brazil, but to play alongside him is a privilege.

I am a player who helps in defence but I have played in a more attacking position during my career and I like to be close the opposition area.

My life's been a rollercoaster.

Football without challenges isn't football.

I have to play. Doesn't matter where.

I had a good first season at Tottenham, but in the second there wasn't a sequence of games. So when I didn't feel happy, I waited for the season to end and then asked the president to let me go to try another challenge.

Football is a game where you have to do a bit of everything if you want your team to have the edge.

Matches are decided by details and you have to be ready to create spaces and help open up defences. It is what I have to do.

Gareth Bale is such a great player. I had watched him before on telly and you could see how special he is.

I have been told you don't have time to think too much when you get the ball in England. In practice it looks even more dynamic than on TV.

Players always wants to play.

At the end of the day, money's never the most important thing.

When you change teams, cities or countries it's obvious there's a period of adaption, but some players can adapt quicker than others.

I will always have a very special feeling towards Chinese fans.

When I left Tottenham for China i knew I would be further away but my main objective was to play because I wasn't playing and I decided to move on.

If you look at my career it has always been about overcoming difficulties in different places.

I had criticism in different clubs I played for. When i played in Corinthians, Tottenham and Barcelona there was some criticism but I always did my work, trying to do my best.

I am very grateful for how I have been welcomed at Barcelona.

It is special to play alongside the best footballer in the world.

I have been playing since I was five and it is a large part of my life.

I am very good friends with Oscar and David Luiz, and Ramires at Chelsea is another one I see.

I consider myself privileged to play alongside the best in the world.

As for Iniesta, he does things in training and in games that I've never seen before. He is an example to follow. You think he might touch the ball four times and yet he only makes one touch. He's unpredictable.

Never mind where you are, you have to fight until the end. It's important you never give up.
