Louis van Gaal "worried" ahead of must-win European game against Wolfsburg

Manchester United manager Louis van Gaal has admitted that he is "worried" about his team's lack of goalscoring threat ahead of the must-win Champions League match against Wolfsburg.

The Red Devils will need to beat their opponents in Germany on December 8 should PSV Eindhoven claim a win over CSKA Moscow, who are already out of the competition.

On Wednesday night, Van Gaal's side failed to seal qualification to the final 16 after playing out a goalless draw against PSV at Old Trafford.

The team have managed just six goals in eight games, which Van Gaal has admitted is a concern.

"Of course I am worried but I know also that goals are coming and going," Van Gaal told reporters. "It is not a consequence of good or bad performances. Today we could have scored at least three goals. It was not the most difficult chances but we didn't score and the next game you can score out of nothing- that is football."

United are currently second in Group B, one point behind Wolfsburg and a single point above PSV.
