Brazil coach Dunga says Manchester United new boy Anderson can become a world great.

The Porto midfield sensation arrived in England on Friday for a medical after United agreed a fee for his transfer earlier in the week.

And Dunga says the Old Trafford fans are in for a treat when the talented youngster pulls on a red shirt next season.

He told The Daily Mirror: "Anderson is an exceptional young player who will be a star at next month's Copa America. He has pace, great footwork and likes to run at opponents.

"He's a great talent with a terrific attitude and he has no fear. With his strength, power and pace he can be a big success in Europe and one of the very best in the world in years to come."

Another man who knows a bit about Anderson is Arsenal's Brazilian midfielder Gilberto Silva, who came up against him in the Champions League last season.

He told the tabloid: "I've only played against him once when we played Porto, but you could see then that he was really fast and had great skill.

"He is also strong, which is important for any forward in the Premiership. I think Manchester United have done a good piece of business by signing him."
