Chelsea midfielder Oscar does not expect to suffer from nerves when he makes his Chelsea debut against Wigan on Sunday.

Oscar, 20, joined the Blues for £25 million earlier this summer and is expected to go straight into Roberto Di Matteo’s side, despite training with the club for the first-time on Friday.

A regular with the Brazilian national team, incleding a starring role at London 2012, the former Internacional player does not believe he will be fazed by the occasion.

He told the London club’s official website: “I hope I won’t feel any pressure. I am not feeling it at the moment. Back in Brazil, when I broke into the national team, people were asking the same question, did I feel pressure at being the No 10 of the team, the new star?

“But I didn’t feel pressure. I think it will be similar here. I am coming into a great team but I feel I can cope with it.”

Chelsea face Wigan at 13.30 BST on Sunday, live on Sky Sports in the United Kingdom, with Oscar expected to make his first appearance in the No. 11 shirt vacated by Didier Drogba earlier this summer.
