CHELSEA have completed the £25million capture of Oscar ahead of his Olympic debut for Brazil tomorrow.

Oscar winners, Blues land Brazil starlet

The 20-year-old playmaker has been signed on a long-term deal by the European Champions after a deal was concluded with Oscar’s Brazilian club Internacional this afternoon.

Oscar, who underwent a medical at a private hospital in West London last week, was not planning to complete his move until his Olympic commitments were over.

But the deal was rushed forward by Chelsea after a work permit was obtained yesterday for the young man who destroyed Stuart Pearce’s Great Britain team in a pre-Olympic warm-up match last Friday.

Chelsea boss Roberto Di Matteo said: “He is a fantastic player, one of the youngest to push through to the Brazilian national team and he will be a fantastic signing for us.

“Oscar is a very exciting young talent, a creative midfield player who scores goals. He will add a lot of options and solutions for us in midfield.”

Confirmation of Oscar’s arrival at Stamford Bridge takes Chelsea’s summer spending spree to a staggering £76m.

Di Matteo’s team have already signed £32m Eden Hazard from Lille, £2m for Hazard’s brother Thorgan from Lens and a further £7m for German international Marko Marin from Werder Bremen.

And Chelsea fans will get an early look at their exciting new attacking midfielder when he plays in Brazil’s opening Olympic game against Egypt in Cardiff’s Milennium Stadium tomorrow.

Di Matteo added: “It will be a challenge to make sure we have the right balance within the team so we will have to see how we fit the team together with all the players.

“The club has always been competitive, looking to improve, get better and fight at the top end of the league so it will only give us a better chance in the Premier League.”
