Jeff Shi was delighted to complete the permanent capture of Marçal from French Champions League semi-finalists Olympique Lyonnais.
The Brazilian bolsters Nuno Espirito Santo's options going into the first round of Premier League fixtures next weekend, and the executive chairman was happy to confirm the club's second signing in as many days.
"We are very pleased Marçal has joined the pack," Shi said.
"Having played over 280 games in top leagues, as well as Champions League football, Marçal will add a huge amount of experience to our young team.
"He is a player with the technical ability to be able to contribute in the build up play from the back, all the way through to threatening the opposition in the final phase.
"He possesses good pace and has a great work ethic, to work up and down the football pitch. Defensively he is very solid and will add to our group with his ability in the air as well.
"Of course, because of his nationality, Marçal was subject to a work permit application, and I am delighted that the panel shared our view on the player’s quality and how he can help Wolves.
"Welcome to Wolves Marçal, you are now part of our pack!"
