Chelsea manager Antonio Conte was not a happy man after his side's 2-0 friendly match defeat against Rapid Vienna.
The Blues were clearly not at their very best as the likes of Victor Moses, Ruben Loftus-Cheek and Papy Djilobodji all featured in Austria.
The Italian says he expected his players to struggle but admitted that they have to improve in their next game against WAC RZ Pellets on July 20.
"This is the first game for us but I knew it would be very difficult after three days of double training," Conte told the club's official website.
"They were very hard sessions, not to enjoy, all about the physical and tactical aspect. I think it was a bit normal to meet these difficulties in the game, but I don't like to lose and it's the same for my players.
"I think the game was very important because we can learn a lot from it. It's important to switch our minds to change. The past is not important, we must build through the work of our present and future.
"We are very happy to open the new stadium but I'm unhappy with the loss. I want to see our fans happy. We'll work very hard because we want to come back and compete for the title until the end of the season.
"I know there is a lot of work to do but we are ready."
