Sir Alex Ferguson has warned United not to make any "stupid errors" in the Champions League after being pitted against Braga, Galatasaray and CFR Cluj.
The Reds boss has pledged to field his strongest side in order to qualify for the knockout stages and is relishing a reunion with Galatasaray after facing the Turkish team in 1993 and 1994.
"We have the experience of playing against Galatasaray in the past and we will always remember the 'Welcome to Hell' banners," he told ManUtd.com. "So it's always a difficult type of match.
"We have drawn Portuguese clubs a number of times over the past few years - the likes of Benfica, Sporting [Lisbon] and Porto - so we have the experience of playing in Portugal on many occasions. Braga are one of the improving teams in that country.
"Obviously, we've never played Cluj before but, after the experience of last year, we don't want to make any stupid errors this time. We will play our strongest team to make sure we get through."
