Michel Preud'homme has conceded that his Club Brugge side need a "miracle" in order to eliminate Manchester United and reach the Champions League group stages.
Brugge welcome the Red Devils to the Jan Breydel Stadium tomorrow night with a 3-1 first-leg deficit to bridge after goals from Memphis Depay and Marouane Fellaini - who added a third in stoppage time - did the damage at Old Trafford last week.
A 2-0 home victory would be enough to see the Belgians advance on the away-goal rule, but Preud'homme admits to being pessimistic over his side's chances.
"Miracles happen sometimes, but they are two goals in front and they are a very professional team," Preud'homme told reporters. "To get a miracle, you need to be perfect and you need the other to not play at his best potential. We have a lot of players out, too.
"If we want to have a chance, we have to be perfect. It will be very difficult, but let's pray. This United team can live with pressure.
"They have it each day, each minute in each game. When you see this team playing, they play on their quality, against Tottenham, against Newcastle, against us. They keep doing the same. I don't think they'll have more pressure if we score, but it's important for our confidence if we score."
Brugge took the lead last Tuesday through a Michael Carrick own goal after eight minutes.
