Manchester United survived a late penalty appeal to defeat Wolves 1-0 in their opening Premier League game on Monday night.
Raphael Varane headed home the winner on 76 minutes before United goalkeeper Andre Onana clattered into Sasa Kalajdzic late on only to escape punishment.
United manager Erik ten Hag later said: "I think we matched the runs, the clean sheet tells that. We played organised but now we have to be better on the ball.
"We gave the ball away too easily. But we got a clean sheet and three points.
"At half-time the message was to be more calm, composed, get more switches in. Get in between the lines more, which we did and caused problems. When they broke we had to match the runs [from the strikers], and you lose that control.
"The creativity was not so good because we gave the ball away too easily.
On Wolves' penalty appeal, he added: "It is difficult. The keeper was brave to come out to meet the ball. The ball was touched before Andre [Onana] dived in, so he did not influence the touch [attempt] from the Wolves player.
"The VAR checked it and said no penalty."
