Manchester United this afternoon completed the signing of Brazil midfielder Kleberson on a five-year contract.
The 24-year-old has joined from Atletico Paranaense in a deal worth stg£5.93million in total.
Kleberson is United manager Sir Alex Ferguson's fifth signing of the summer, and his arrival comes hard on the heels of Portuguese starlet Cristiano Ronaldo, who joined from Sporting Lisbon for £12.24million this morning.
Kleberson said: "To be the first Brazilian to sign for United is special. This is the biggest opportunity of my life.
"I had offers from other clubs but they weren't Manchester United. What I promise the fans is to give my all on the pitch from the outset."
Kleberson and Ronaldo have followed David Bellion, Tim Howard and Eric Djemba-Djemba into Old Trafford after Ferguson sold David Beckham to Real Madrid for £25million and Juan Sebastian Veron to Chelsea for £15million but missed out on Ronaldinho.
Ferguson said: "We're delighted Kleberson is joining us because we've been chasing him for quite a few months.
"He played in the World Cup final for Brazil, and his then coach Phil Scolari said he was first choice every time in the team.
"The new Brazilian coach Parreira says the same. He is a young, athletic midfield player who can play in a number of positions.
"One of the reasons we sold Seba Veron was because we knew we were getting Kleberson - that shows how highly we regard his talent."
