Manchester United manager Louis van Gaal says PSV Eindhoven should not be underestimated ahead of tonight's match at Old Trafford.
The Red Devils will qualify from the group stage of the Champions League if they take all three points against Phillip Cocu's side.
And the Dutchman is eager to avoid last-minute pressure and secure qualification as early as possible.
"You always have to win your home matches and that point in Moscow is very important for us," van Gaal told reporters.
"I said after that result that we are on schedule and I still think I am right about that. If we beat PSV, then we will have qualified.
"It is very important to win [today], but it is not easy because every game you have to play you cannot say we will beat them.
"PSV also beat Wolfsburg and I think that they are a very good team. They also beat Manchester United of course."
Asked to comment on rumours linking Cristiano Ronaldo with a return to Old Trafford, he added: "We are looking at all players, not just Ronaldo.
"But these players are mostly ungettable. With Ronaldo, let's wait and hope."
