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.
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.
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 played for Atletico and Internacional and then moved to Ukraine with Shakhtar Donetsk. My family supported me a lot and I'm very thankful for them.

When I was 10 I started playing for Atletico Mineiro and that was the start of my professional career.

Obviously I'm not happy when I miss the passes so I look to get that right. I work very hard on that.
