Manchester United defender Rafael has confessed that he is disappointed to see his fellow Brazilian Oscar join Premier League rivals Chelsea.

Twenty-year-old Oscar completed his switch to the Blues last week for a fee in the region of £25m.

Reflecting on the move, Rafael feels that Chelsea have added an exciting prospect to their squad ahead of the new season.

"He's an incredible player. When I see him doing these amazing things it almost makes me feel sad to think that he's gone to one of our rivals," Rafael told FIFA.com.

Oscar and Rafael are both part of the Brazil squad that is currently competing for gold at the London Olympics.
