Manchester United midfielder Juan Mata cannot put his finger on why the goals have dried up.
United have scored just five times in their last six games in all competitions.
Mata said: "I don't know why. I'm sure we will create chances again and I'm sure we will score goals again because we have very good strikers and very good midfielders. The chances will come for sure, hopefully this Saturday.
"We've played very good football in some games, especially in November and December. We have to look back at how we did it and to do it again - because I think we can do it.
"The way the manager wants to play is attractive for the fans and attractive for the players. I really like it. It's just a matter of doing it how he wants."
