The reigning English champions will take on local rivals United at the Etihad Stadium on Sunday having suffered two defeats in a row against West Ham United and then Newcastle United in the League Cup.
"My view of City overall has not changed," Scholes said in his column for The Independent. "After a week which has brought defeats to West Ham and Newcastle there is something about them, you might even call it a touch of arrogance, that they do not have to take their opposition into consideration.
"I realise that it is a point I have made before, but I don't think the central midfield is right, and that they are getting the best out of Yaya Toure. He still looks laboured to me, you might even say he looks a bit bored. He has the ability to step it up when he wants to, and that could be the case on Sunday."
United currently sit four points behind third-placed City in the Premier League table.
