Ruben Dias admitted Manchester City's 3-0 Community Shield defeat to Arsenal was "not good enough" after captaining the side in Enzo Maresca's first competitive game in charge.
City were second best throughout, falling behind in under a minute when Riccardo Calafiori slotted home. Kai Havertz headed a second before the half-hour mark, and Martin Odegaard added a third shortly after the break after putting Gianluigi Donnarumma down and scoring into an open goal.
Dias: 'A lesson to be learned'
Speaking to TNT Sports, Dias thanked the travelling fans and acknowledged the performance fell short. "First of all, thank you to the fans who came, obviously it is a long distance. Thank you to all of them for coming so far. It's the beginning of the season but it's not good enough," he said.
"Many things are changing and a new manager as well. Still, the way the game starts, it just sets you off right away. They get comfortable playing their game. But in the end, this is just starting and the most important thing is that we're already looking forward, and we will be ready for our next game."
He added: "I joined midway [through pre-season]. This is the third game since I've been back. The feeling has been good. Obviously, today it's frustrating and it's a final we want to win it but there is a lesson to be learned from the final, let it be this one because there's a lot more coming."
Positive energy despite defeat
Dias insisted the group retains a positive atmosphere despite the defeat and upheaval. "Well it's a positive energy," he said. "The feeling is there is a lot of work to put in. It's part of a new transition for things not to be so perfect in the beginning and you need to push through, you need to keep on working, you need to communicate, you need to make things work between us and, obviously, with Enzo as well.
"I feel like it will. We are in a very good way. But we need to keep on working and there is obviously going to be lots of challenges along the way and that's it. [We need to] stay positive, look forward. We have our first Premier League game very soon."
City begin the new Premier League season next Sunday when they host Bournemouth at the Etihad Stadium.
