Louis van Gaal has called on his side to "come out of these moments" and end the goal drought as United welcome CSKA Moscow to Old Trafford on Champions League Matchday Four.
Remarkably, the Reds have not scored since the 1-1 draw in the reverse fixture in Moscow 12 days ago, a drought that has now stretched to over 300 minutes in all competitions.
LVG admitted at the weekend that the lack of goals is a concern, but the boss remained positive in his press conference on Monday and insisted that he is seeing improvement from his players despite recent struggles.
"Football is scoring goals, it's a bad period when you don't score but it is a moment in a process and I know that my players can come out of it.
"I think we are improving every week and you can see that because the opponent has not scored against us in the last three games, so now we are the best defenders in the Premier League.
"I want to see the next process, finishing the chances we create which we have not done because our opponents has played well in defence, so it is more difficult." said the boss.
Russian league leaders CSKA come to Manchester in good form after two domestic wins in a week, including Saturday's 2-0 home success over FC Ufa in which former United man Zoran Tosic netted.
They are currently unbeaten with 11 wins and three draws so far in the league this term and have an identical Group B record to us with four points from their opening three games in Europe.
United midfielder Morgan Schneiderlin is a doubt for the match after missing training on Monday, and Paddy McNair, Luke Shaw and Antonio Valencia are all still out.
There are no new injury concerns for the Reds.
CSKA defender Alexei Berezutski and midfielder Roman Eremenko are both doubtful for Leonid Slutski's side.
The last time these two met at Old Trafford in 2009, the match ended 3-3 with Paul Scholes and Valencia scoring late for the Reds.
