Chelsea boss Roberto di Matteo is delighted to have clinched the signing of Internacional midfielder Oscar. The 20-year-old arrives from Internacional to join compatriots David Luiz and Ramires in the first-team squad, though he is currently on Olympic duty having helped beat Team GB in a friendly last week.

"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," Di Matteo said.

"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."
