Bournemouth boss Eddie Howe admits their defending wasn't good enough for defeat at Manchester United.
The hosts, as expected under new caretaker manager Ole Gunnar Solskjaer, looked to attack from the off and Howe's side were powerless to prevent the goal in the 4-1 defeat.
Howe said, "It's a tough day and a disappointing performance.
"Defensively we weren't great, with the ball we weren't great and that's a bad mix coming to Old Trafford.
"They played in the way we expected but we didn't with them well, we didn't defend crosses well and allowed them too much time.
"They have players in every position that can hurt you, but we have to learn from this game."
The manager continued, "We've been through a tough period, the fixture list has been extremely unkind to us.
"We've had a real run of successive games and the injury situation is very difficult as we have stretched resources.
"Those injuries maybe meant that I had to play a system I wouldn't have played ideally.
"That's combined with confidence but the main focus for me is that we can control our destiny, we have to change this moment and that's where the focus lies."
