The 31-year-old defender arrived from Lyon at the weekend – hot on the heels of the club smashing their transfer record to sign teenage striker Fabio Silva for £35million.
He comes in after helping the French side reach the Champions League semi-finals last season and is aiming high at Molineux as well.
"I am very excited. I want to make history here, I want to win every game, and I want to help my team. This is the reason I came here," said Marcal.
“I will bring experience and a fighting attitude. This is my normal character, and I give my best all over the pitch.
“I am here to give all my energy. In every match, every training session, I will do my best to win the game, win the championship and win the trophies.”
Marcal, who made 77 appearances for Lyon, cost around £1.8m and has signed a two-year deal.
He played on the left of a back three in their run to the last four of the Champions League – beating Manchester City in the quarters before bowing out to eventual winners Bayern Munich – and is also comfortable as a wing-back.
“Firstly, the Premier League for me is the best championship in the world. I think every player wants to play Premier League," said Marcal.
“I am very happy to come and play in this championship and this, for me, is a dream.”
Marcal is now one of the most experienced players on Wolves' books, having also had spells in Portugal and Turkey.
He added: “Wolves is very special. I follow a lot of the players because I like these players very much.
"I like Rui Patricio, (Joao) Moutinho, and I followed these players a long time and I will like playing with them.
“Now, everyone knows who Wolves is. In Brazil, everybody talks about this team because we are very strong, and this shirt is beautiful. I want to bring it every weekend, every match.”
