Manchester United striker Zlatan Ibrahimovic says they must be more ruthless in attack.

Ibrahimovic has plundered 13 goals in all competitions to maintain his end of the bargain since joining United on a free transfer in the summer.

He said: “We have created many chances and sometimes you win 1-0. But you need to close (the game) at 1-0.

“It hasn't happened yet, but we are working hard. We have learned now that we have to score more than one goal to get the three points.

“We want to kill every game we play. But as long as you create the chances you will score.

“You need to get the three points also. That is more important, but you can get the three points by winning 1-0 and not only 4-0."
