Paul Lambert bemoaned a slow start as Villa went down 2-1 at home to Newcastle.
Lambert was frustrated his team didn't show the usual drive and energy from the off against the Magpies.
Villa boss Lambert believes that was a fundamental reason for the loss, as well as the concession of two poor goals from his perspective.
He was happier with the second half display but is keen for his emerging team to score first in games, so they don't give themselves a mountain to climb each week.
He said: "It was frustrating, very much so.
"We never got going in the first half. It was unlike us. But we can't lose goals like the way we did.
"We started the second half really well. But the first half, we lost a really poor goal and the second I thought was even worse.
"They get back into it then. The impetus and ascendancy was with us. But you can't defend that way.
"We don't set them out to play that way. You have to give Newcastle credit for starting the game well. We are not a team who can play slow football. We don't have that knowhow yet to play that way.
"A big part of our game is our energy and tempo. We started slowly. In the second half, it was much more like us.
"It wasn't like us, especially in the first half. In the second half it was a lot better.
"You pick them up and go again on Monday now. We have Norwich on Saturday.
"I can't fault them for effort. They gave me everything they had to try and retrieve it. But the disappointing thing was the two goals.
"I am not one for making excuses. We got beat because we didn't start the game in the right manner.
"The frustrating thing in the games we've played is we have always conceded the first goal. We have had to come back from that. That's a lot to ask every time. It's a lot to do. It's disappointing to start in the manner we did.
"But I can't fault my team for effort. I'd like to get results and more points. But I can't fault them for the way they try to do the right things."
Lambert is also waiting on news of Jores Okore, after the defensive ace came off injured on the half hour mark.
He added: "I think he's hurt his knee. I will speak to the doctor and see what his opinion is and what he thinks."
