Manchester City midfielder Bernardo Silva insists no-one inside the club are getting carried away with their unbeaten record this season.
Their 18-match winning run came to an end with a goalless draw against Crystal Palace on Sunday and Silva will hope to avoid a surprise defeat against Watford on Tuesday.
"In football, you are never invincible," Silva told Sky Sports.
"Of course it has been good up until now. In the Premier League, we haven't lost yet a game so it is very good for us and our confidence.
Manchester City will aim to return to winning ways against Watford without Gabriel Jesus and Kevin De Bruyne.
"But we have to keep working the same way we have been doing from the start of the season. That is what we will try and do.
"It is good for the confidence not to have lost yet."
