But Kompany believes that Watford will help City's title bid - by spoiling the party for their rivals later in the season.
Kompany said the following to Express and Star: "I'm confident they will take points off our competitors.
"I'm convinced they will (surprise a few teams) – they don't behave or play like a Championship team that has just been promoted.
"They are the typical type of team who is geared up to get big scalps because they have enough quality to play themselves out of situations when they are under pressure.
"The other thing is their key players work hard and that's always a good mix."
