The 24-year-old, who joined Barca from Lyon in 2016, was linked with a summer switch to Old Trafford after refusing to comment on reports back in March that he wanted to jump ship and play in the Premier League.
The Red Devils are in the market for a new stopper but it will not be Umtiti, who has extended his deal with the Catalans and had a 500m euros release clause inserted into his new contract.
And, as he prepares to go to the World Cup in Russia with Les Bleus, the Cameroon-born ace has been quick to deny he ever thought about a switch to the Theatre of Dreams.
"I was asked if I wanted to stay or go to [United] but I didn't want to talk about that, above all because I was with the national team," he told reporters on Monday.
"I just said the word 'joker.' I don't know how that word is interpreted [in Spain], but you can interpret it as you wish.
"The priority was to renew here at Barcelona, as I have done. It's my home. It's a dream to play here, with the best players at, for me, the best club in the world. I don't see myself playing for another team.
"I am really happy here and I have everyone's confidence, so I couldn't leave. That's it."
