Douglas Luiz says joining Aston Villa is one of the best days of his life.
The former Manchester City midfielder has joined Villa in a 15m deal.
Luiz told Club TV: Today is a really happy moment in my life and in my career.
It's the start of another stage in my life. I've got another chance to play in the Premier League.
I'm really happy to have signed today and it's the start of something great.
I hope I can be a leader in the team. I hope I can help by bringing the ball out from the back and, although I don't speak a lot of English, I hope I can help out by shouting orders from the back and live up to all the expectations as best as I can.
I hope we have a great season and win a lot of games.
Right now I'm confident in saying that, God willing, I can shine in the Premier League.
So I hope I cannot just talk the talk but also walk the walk and that's my main aim.
I came here to learn but, more than anything, to dream big and to be a leader on the pitch."
