Premier League - De Jong bullish over derby
City go into the clash with second-placed Manchester United two points clear of their local rivals.
The Blues emerged triumphant when the two sides met at Wembley in last season's FA Cup semi-final and De Jong is confident they can do the same again.
"Everyone believes we can go there and win," said De Jong, quoted in several national newspapers. "We're going there as number one and the aim is to stay number one.
"We feel we can do that but United will be confident as well, and they're playing at home, so it's a massive game for both of us."
