The striker will follow Neymar in committing to the club, with confirmation of the deal potentially coming before the end of 2016.
Luis Suarez will become the next Barcelona star to sign a new contract, according to president Josep Bartomeu.
The Uruguayan’s six-year deal comes less than two months after his forward partner Neymar commited to the club until 2021, and it could be confirmed before the end of 2016.
Javier Mascherano and Ivan Rakitic have also recently penned fresh terms, with Lionel Messi expected to follow suit.
“Suarez is going to renew [his contract] now. It’s already done,” Bartomeu told Radio Vision. “There are only a few small details outstanding. In the coming days or weeks we will announce it.
“Maybe, why not, as a big Christmas present. Not for Luis, who already knows that he is going to continue here, but for football fans.
“For them he is a very important character who forms part of this spectacular front three that we have at the club.”
Suarez, who arrived from Liverpool in a deal worth around £65 million two years ago, turns 30 in January and Bartomeu hopes to the player sees out his career at Camp Nou.
“We want [his contract] to be even longer, but for the moment he will sign until 2022. You have to adapt to the rules, which have a maximum contract length.
“We want Luis Suarez to be at this club for many years. And when he retires he will always be welcome at Barcelona.”
