The Senegal international's comments come amid reports of growing interest in the 25-year-old from a trio of Premier League sides.
According to the Daily Mail, Ndiaye's performances for Everton have attracted attention from Arsenal, Manchester City and Manchester United, with the report suggesting he has turned down offers of new terms at Goodison Park as he eyes a move to a higher level.
Everton are understood to retain control of the situation, with Ndiaye under contract until 2029 and manager David Moyes reluctant to sanction a sale. Manchester United are said to be the club showing the most concrete interest at this stage.
Should a significant offer arrive, it could represent a substantial return on Everton's initial outlay. The Merseyside club paid Marseille around £15m to sign the winger in the summer of 2024, a fee that now looks modest given his impact in the Premier League.
Ndiaye's reflections on his time at the Stade Velodrome, given in an interview with France Football, painted a picture of a young player who arrived in the south of France without fully appreciating what awaited him.
"On the day I signed, there was the player in me who wanted to take the next step, but also the child who was dreaming."
He described the reception he received from supporters as overwhelming, particularly given his modest expectations at the time.
"And then, the welcome from the fans. I'm lost for words; it was so crazy. I hadn't made a name for myself yet. I thought that if there were three people there to greet me, it would already be the end of the world."
Ndiaye scored three goals in 30 Ligue 1 appearances during his solitary season at Marseille, a return he acknowledged fell short of what the club expected from him.
"At a club like that, you have to perform very quickly. I struggled, I won't deny it."
He explained that the step up came too early in his development, having arrived in French football's top flight without the academy background or top-level experience that the move demanded.
"The reality is that I didn't really go through a youth academy, and I'd only had one professional season in the English second tier. So, there were still gaps in my game for a top French club that has to be among the best. I lacked a bit of experience at the highest level."
Looking back, Ndiaye suggested the timing of his departure from Marseille was a mutual decision rather than one forced upon him.
"When we discussed Everton's interest with the club's management, nobody wanted to keep me — at least it was clear."
He went on to reflect on how differently things might have unfolded with more experience behind him.
"It's certain that if I'd arrived two years later, with two Premier League seasons under my belt, I'm sure the story would have turned out very differently at OM."
With his stock now considerably higher following two productive seasons in England, Ndiaye's words will be read in Marseille as an open door, even if any reunion remains hypothetical for now. For Everton, the priority is clear: keep their winger happy, keep him out of the shop window, and hope that suitors circling from Manchester find other targets before the transfer window gathers pace.
