Southampton boss Ralph Hasenhuttl was left frustrated after their 2-1 defeat at Norwich City.
Hasenhuttl felt they performed well on the day.
"Dominance without scoring is not really helpful, it only costs energy," said Hasenhüttl, discussing the first half.
"What was fact was that in the second half the opponent tried with the motions to put us on the back foot and they managed it, then we must play 1-1. This is what I have to say.
"Then we can never concede a goal like we did the second, where we have a clear one-against-one in the air and we don't man-mark in the situation, and for Alex [McCarthy] I think there's a chance to make the save there. It's too easy. It's too easy, and then it's always tough. Normally you cannot lose this game, but you see in football everything is possible."
Hasenhüttl did raise a question mark over Teemu Pukki's seventh-minute equaliser, though, with a strong claim for a foul by Milot Rashica on Kyle Walker-Peters that led to the start of the Norwich attack.
"For me it was a very bad moment to concede the equaliser, and the way we conceded it was also discussable," he said. "I think it was a clear foul.
"He is running past him and if this is not a foul then I don't know to be honest, but the referee decided to let it go. But then we still had enough players in behind the ball, but we couldn't defend it."
