Chelsea winger Willian has admitted he feels a little uneasy ahead of Brazil's friendly game against Argentina.

The game will be played at the MCG in Melbourne on Friday, four days after a siege in the city, which left one man dead.

The attack occurred only 24 hours after seven people were murdered in London – the city where Willian lives.

When asked if he felt anxious about the match following the attacks, the 28-year old answered: "Yeah, I'm a little bit worried.

"But the players have to think about the game.

"There is people responsible to take care of our safety and we have to be prepared for the game and don't think about that."
