Sasuke Uchiha and Gaara of the Sand Village have had a lot of tussles since they initially met each other during the “chunin tests“. After Gaara had utilized his dominance of the sand to bring down Rock Lee in a merciless style, Sasuke was the next to battle the Jinchuriki. In spite of the fact that their battle was intruded on, the two still held a competition toward each other.
Presently, years after the fact, the two ninjas are in altogether different pieces of their lives, having both mellowed out extensively and an outline for an up and coming scene of Boruto: Naruto Next Generations is implying that the pair of apathetic warriors will collaborate against a typical enemy.
Twitter User Organic Dinosaur translated Boruto Episode 121’s abstract, demonstrating that Sasuke and Gaara will unite to endeavor to cut down Urashiki of the Otsutsuki Clan:

Gaara had a more persuasive part in Sasuke’s life than you may initially think, explicitly he’s the motivation behind why the last individual from the Uchiha family learned one of his most dominant methods. Following the underlying one on one battles of the Chunin Exams, the understudies were given a brief period to recuperate and prepare for the following round, with Sasuke explicitly learning under Kakashi for his up and coming battle with Gaara. During this concise preparing period, Sasuke took in Chidori from Kakashi, the electrical assault that he centers in the palm of his hand to convey a final knockout.
