Flick joined the "Blaugrana" in July 2024. He has since led them to two consecutive La Liga titles, securing the second this past weekend with a 2-0 victory over Real Madrid in El Clásico.
"I'm truly happy with the signing. The club has shown confidence in me and my team for another year or two of work. Many coaches would be thrilled with a four or five-year contract, but in Barcelona's case, it's good to keep it limited. I really appreciate that," Flick stated, according to the BBC.
"We're going until 2028, and then we'll see if everything is in order. If so, we can opt for another year. The club has the right, I have the right, and I think it's a good agreement," added Flick, who replaced club legend Xavi Hernandez two years ago.
Barcelona celebrated their championship win three rounds before the end of the season, with a chance to equal the historical maximum of 100 points.
