City did the double over Chelsea last season and De Jong hopes that can given them a mental edge.
"The fans can do a lot for us," he told City's website. "At home, they can be the twelfth man from the first minute onwards. That will be a big help and we expect a lot from them tomorrow.
"Everybody knows what happened last season. It was a special game for the club and the players. We are all looking forward to playing this game."
