Barcelona hero Deco is convinced by the quality of new signing Arthur Melo.

The former Gremio midfielder was presented to the local media on Thursday.

Deco said: "I think Barça made a great signing with Arthur Melo, a player who has enough class to play at the Camp Nou.

"I've seen him play many games with Gremio de Porto Alegre and, above all, he a great quality, something essential for any footballer who is linked to Barça.

"Playing at Barça is not easy and what is needed, above all, is to have weapons to play in a team that has a level of control of the ball and very high possession. And then you have to have that same quality to unbalance with the ball.

"I think that Arthur has a class to do it in the shirt of Barcelona, something that is not available to everyone."
