City have not won a trophy for 34-years and with their huge financial backing, silverware is one of their top priorities this term.
City open their Europa League group campaign with a trip to Red Bull Salzburg and De Jong feels the Europa League is very much in their sights.
"We expect to win something this season.
"Being the first one for so long, it doesn't really matter which it is.
"Once we have got the first, I expect a few to quickly follow. We are in four competitions and we could win any of them.
"Our long-term project is to win the league but if you look at the players we've signed, they all have the winning mentality."
David Silva is poised to start that match in Austria and De Jong is tipping the Spaniard to make a big impact for the club.
"I've seen quite a lot of him over the years and we are very excited to have him.
"David reads a game very well, he has a terrific left foot and is very skilful."
City boss Roberto Mancini is also looking for Silva to show what he can do against Salzburg.
"David is now ready to play. When he arrived was he was only here a couple of days and then went off with Spain," said Mancini.
"He came back and then went away again but now he is here with us.
"I have no doubts he'll be able to cope with the English game. He's a fantastic player.
"When you arrive in the Premier League it is normal to have a few problems at first.
"But when David's played a few games you will start to see the best of him."
