Neymar believes that a "change of attitude" was required from Paris Saint-Germain in order for them to save their season in the Champions League.
The Ligue 1 champions reached the final of the competition in 2019/20, eventually losing to Bayern.
This season, however, has been a struggle so far as prior to the win against Manchester United at Old Trafford on Wednesday, they had won two games and lost two. If they had lost against the Red Devils, it would have represented a major blow in their qualification hopes.
They would have had to rely on the other result in the final match of Group H to qualify.
Neymar insists a change of attitude and a desire to not play in the Europa League motivated he and his team-mates on to victory in the return game against United.
"That is why I said that we needed to change attitude or else we could forget about our Champions League dream," the Brazilian told Eleven Sports.
"But we have changed. And today our dream has more life in it. Of course, I have never been eliminated in the Champions League [group stage] or played in the Europa League.
"That never crossed my mind and it never well. When these difficult moments come, I am able to evolve and take my responsibilities. I did not come here to play in the Europa League."
