Jose Mourinho has admitted that Manchester United were "defensively awful" in the first half of Saturday's 2-1 win against Bournemouth at the Vitality Stadium.
Callum Wilson put the Cherries a goal up on 11 minutes and continued to impress, but Anthony Martial levelled the scores 10 minutes before the break.
Marcus Rashford then came up with a late winner for United, who have moved into seventh spot in the table, just two points off fourth-placed Arsenal.
"It was the whole first half. I said at half-time I was the luckiest manager in the Premier League in a half when it should be like 5/6-2," Mourinho told BT Sport.
"We were defensively awful. As a team we didn't press or do any of the week we did in the week. People watching this game will not believe how hard we worked this week.
"The first half was a disaster. The second half was much better. We created lots of chances and deserved to score before the 92nd minute."
