Dembele, who joined Barcelona from Borussia Dortmund for £135million last summer, has had a stop start spell at the Nou Camp.
Injuries have limited his involvement and he has made just 11 appearances for the Catalan giants this season.
However, Dembele could quite easily have ended up at Liverpool instead of Dortmund.
“I spoke to three clubs (when leaving Rennes),” Dembele told French magazine Onze Mondial.
“Dortmund, Liverpool and Barcelona.
“I had an appointment with FC Barcelona. I told them, ‘For next season, it will not be possible.
“But the next time you contact me, I’ll come. And that’s what happened.”
Despite his inauspicious start to his Nou Camp career, Dembele is desperate to turn things around.
He added: “I was injured but I was able to keep myself calm and serene.
“I thought that it was better that it happened at the start of the season than at the end, when the most important games come.
“The first games have helped me to adapt. I’ve hired an osteopath and a cook. Diet is essential for a player and I have to look after myself.”
Barcelona face their nearest title challengers Atletico Madrid next on Sunday (3.15pm).
