Manchester City midfielder Kevin De Bruyne feels there's more to come after their Community Shield final triumph on Sunday.
“It was a really tough game, you can still see it's still early in pre-season that it's an open game. Both teams are not physically ready yet with other players coming back," he told BT Sport.
“It's nice to see the competition, to fight each other this year again and that is what it is all about.
“It's always going to be tough, there is moments in the game that we're going to control and moments they were going to control, especially in this moment of the season.
“I think we defended well at times. We could have scored, they could have scored, it was a really open game.
“The good thing is we always play the same system so we know what we need to do and the style we play but obviously some came back two days ago, the rest of us have trained for two or three weeks.
“Pre-season is more commercial these days than it is training, so I think the month of August is really important to get your fitness up, to get game time, because most of the time it was their first 90th minute of the season."
