I just want to continue doing what I'm doing, playing well and starting the games - but I want to score, too.
All I ever wanted was to play regularly and now that I'm doing that, there's no doubt my confidence is higher and that helps any player.
That's what Brazilians are like - we're always having a laugh, we're always smiling, and my aim is to bring this spirit into the dressing room and onto the pitch, to play with a smile on my face.
I would never do anything that would harm me, and I am totally against using any kind of resource, illicitly, to benefit myself in any way.
I think I am strong on the field, I am versatile, I can play in several midfield positions. Some coaches like that, it grabs their attention, it is a big deal for me.
I suffered a lot of criticism from the press and the fans, but I always kept motivating myself, working. I never dropped the shuttlecock.
I think my ideal position is to join the attack a bit more like I did at Shakhtar. I played more as a box-to-box midfielder, so I played a little bit further forward.
Michael Carrick helps me a lot day-to-day. We always talk and he tries to help me with my positioning on the field. He's someone who always talks to me, which is important for adapting my football to the Premier League.
I want to be a big player and be part of the history of Man United. I already am, but I want to make history here at the club and to win some trophies, so that is my goal at Man United.
The English league is difficult and has lots of big clubs but I think the derbies are the best games to play so, when we see the fixture list, we look at those games first.
It's hard to pick out a single team, because there are so many big games here in the Premier League, obviously there are the top teams like Liverpool, City, Chelsea, I think those big games, the 'big six' are always good. We always look forward to them, we all want to be on the pitch and to win them.
We are all the same regardless of skin colour, hair and gender. We came from the same place and we all go to the same place when it's all said and done.
From my personal observations, the Spanish style of play, with a large number of passes, is somewhat similar to the Brazilian one.
For me, I think the toughest player I came up against was Messi; he's out of this world, he's a genius. For me he's the best in the world, a great player and I think he's the toughest opponent I've played against.
When you play at a big club, there will always be competition - I'm used to it. It's been like that from day one at United.
My personal aim is to play a lot of games, put in great performances, do my best to help the team. Not get injured, obviously.
