Wesley has joined Roma for a fee of €30m, signing a €2m-a-year deal to 2030.
He told Roma's media channels today: "It was very difficult to leave Brazil, but coming to Europe has always been a dream of mine. Now I'm at a big club like Roma, I'm very happy and I feel the responsibility. I would choose to leave Brazil again to come here.
"I'm a very attacking player. I have a lot of work to do and I still have a lot to improve on. I like to play wide. I can play in a back four or a 3-4-3, always playing wide. As I always say, if I'm good at attacking, I can also be good at defending, and vice versa. That's why I hope to make a good contribution."
Wesley added, "Roma's fans remind me a lot of Flamengo fans. The fans are incredibly passionate, and today I saw it at the airport, I repeat, at 6:10 on a Sunday morning. There were so many people there, people who love this club so much and want the best for it.
"That's why the message I can send to Roma fans is that I will always give my all. When I can't get there with quality, I'll put in the desire and pace; that's what I've learned. Forza Roma!"
