Manchester United boss Louis van Gaal was happy with the second half performance of his team, less with what he saw in the first 45 minutes of the game against Sunderland.
The Red Devils registered a much-needed win this afternoon but were far from convincing in the early stages of the game.
And the Dutchman believes his side were still suffering the effects of last week's defeat against Swansea City.
"We started not so good in the first quarter of the game," van Gaal explained.
"Maybe we were nervous after [the] Swansea [City defeat]. But then we created chances and stopped giving them away.
"In the second half we played very well.
"We created a lot of chances and scored goals, so I was very happy then."
The Dutchman opted to take off £59.7m winger Angel di Maria at half-time, a decision that proved beneficial to the Red Devils.
"I want to win. I have to observe and analyse," van Gaal said.
"We were better in the second half so I cannot say it was the wrong decision. We have to give him time to adapt and lift his confidence again.
"He’s a human being and makes mistakes like everyone else."
The win means United move up to third place in the Premier League with Arsenal in action on Sunday at the Emirates against Everton.
