Manchester United boss Erik ten Hag was happy with their 4-2 defeat of Sheffield United.
The Blades twice took the lead on Wednesday night, but Bruno Fernandes' double saw United go 3-2 ahead before Rasmus Hojlund struck late to settle the game.
Ten Hag said, "It was for the crowd a good game. Four goals and many chances we created.
"I think we played quite well, also creating many more chances. Many positives. But also negatives. Conceding two goals from give-aways. It's unacceptable.
"We want to play dynamic, attacking football. That is what we want to see. Since the winter we create lots of chances and also score a lot of chances."
On Fernandes, he said: "He is really leading the team. I'm very happy with his performance."
On Casemiro playing at centre-back, he added: "He's playing very good, we know he can play there.
"Two give-aways. It can't happen, it's unacceptable. We have to get it out of our game."
