Jose Mourinho says Manchester United cannot become complacent after beating St Etienne 3-0 last night.
The Red Devils defeated the French club in the Europa League Round of 32 first leg thanks to a Zlatan Ibrahimovic hat-trick and will return to the Stade Geoffroy-Guichard for the return bout next Wednesday.
"The result is really good, especially after a first half when we didn't play well - far from it. It is a really good result but it is not over, it is still dangerous," he told MUTV.
"I've had crazy experiences in football.
"I was losing against Tottenham once, 3-0 at half-time, and we drew 3-3.
"I was winning, it was Real Madrid against Galatasaray, we won 3-0 at home and then were losing 3-1 in Istanbul [the tie ended in a 5-3 aggregate win for Real].
"I have been through so many crazy experiences that I believe in anything. We have to go there, defend well, not concede and try to score a goal that will put them in a very difficult situation."
