The Brazilian hitman, part of Barca's devastating attacking trio that hit 122 goals last season as the club won the treble, was linked to a move to United who needed a striker and went on to sign Anthony Martial.
"There were talks but nothing came of them," Neymar told ESPN Brazil. "There were rumours but I never received an offer."
The 23-year-old added his aim is to stay at the Catalan club.
"I hope we have a dream season. I want to have consistency with my work along with my colleagues and continue to win titles," he said.
