Manchester United boss Alex Ferguson believes that a victory over Otelul Galati tomorrow is crucial for United's Champions League campaign.
A win at Old Trafford could set up a Group C decider with current leaders Benfica.
"We have to win," Ferguson said. "We're at home and I expect us to win. If we do that, it's in our hands when we play Benfica at home.
"I expect Benfica to beat Basel as they're in a bit of disarray with Thorsten Fink going to Hamburg.
"We'll hopefully win our game and, when we play Benfica at home, it'll be the decider."
United are currently second in Group C with five points from three games.
