Arias explained his decision to join Wolves in a press conference to announce his departure from Fluminense. He told reporters: "I've always expressed my dream of reaching a major European league, and this time, God has given me an opportunity that's good for everyone, it's good for me, it's good for the club, and I'm having this chance to fulfill my dream of reaching the best league in the world.
"Until my last day, I honored this badge and this jersey, which are above anything, anyone. But I always dreamed of this, just as I believe everyone has a dream—every fan, every person has a dream, regardless of what it is. I always hoped for this dream, and thank God, today I have the opportunity to leave a lasting mark on the club, something very positive for Fluminense, and to achieve my dream of playing in the Premier League."
