Barcelona were concerned Umtiti's clause would be met amid reported interest from Manchester United, and therefore, according to ESPN FC, negotiated a £437m (€500m) release clause in the latest version of his agreement with the club.
"The Frenchman will be putting pen to paper on Monday in the Josep Sunol lounge at Camp Nou".
With Umtiti in the side, Barcelona have lost just once in 48 games, winning 83% of the time, a figure that drops to 57% whenever he hasn't featured.
However, he has committed his future to the team and there is no mention of what his new release clause is in the press release from Barcelona.
"I'm nervous today because this is a dream that continues", he said.
"From my very first day here, I felt like I was at home, and now I want to stay here for much longer".
The France worldwide, who is preparing to represent Les Bleus at the World Cup later this month, penned a new five-year contract extension at Barcelona on Sunday night.
Sergio Busquets is also in line for a new contract but Barcelona will now turn their attention to bringing in new players.
