Manchester United midfielder Ander Herrera had mixed emotions after victory at Bournemouth.
Herrera concedes they face a hiding at Champions League opponents Juventus if they repeat their Dean Court mistakes.
He told manutd.com: “Of course, the feeling is fantastic as you all know because you all enjoy it as much as we do. But we want to win games more calmly, and don't let the game go on until the last minute without winning the game.
"I think the second half was fantastic and I think that's the way we have to face every game this season, with the ball, with confidence, trying to hurt them with all the offensive players moving and making it really, really difficult for them because we have some amazing offensive players. But we have to improve because if they score two or three goals in the first 20, 25 minutes, maybe we lose the game.
“If we want to win against Juventus, against Man City, we cannot concede what we did in the first half today, even more with the team we have. When I see some players training or some players the way they played in the second half, Anthony, Jesse when he came in, Marcus Rashford, we have to win a lot of games with these players. So let's try to improve for the next game, from the first minute.
"We have to face the game the way we did after 30, 35 minutes because I think also for the last ten minutes of the first half, we played really well. But if we want to be in the top four soon, we have to do it from the first minute.“
