Ruben Amorim has renewed his contract as Sporting CP head coach until 2026, the club announced on Tuesday.
Amorim, 37, had been linked with Premier League clubs Chelsea and Aston Villa earlier this season but no move ever materialised.
The former Portugal international moved to Sporting in 2020 after a positive spell with Braga and went on to guide the club to their first Primeira Liga title in 19 years in 2021.
Last season they finished as runners-up in Portugal's top tier, though after 13 games of the 2022-23 campaign they find themselves fourth and 12 points adrift of bitter rivals Benfica at the summit.
They also finished third in their Champions League group, subsequently dropping into the Europa League.
Nevertheless, Sporting remain committed to stability, convinced in Amorim they have one of the world's premier coaches.
"This renovation demonstrates a lot how Sporting CP works today: with discretion, efficiency and direction," president Frederico Varandas said.
"It is also a very strong sign of how today Sporting CP is a strong and stable club, with stability being the basis of all success.
"A contract of this length always obliges the people who sign it to see themselves 100 per cent in the sporting project and that there is extreme trust between both parties.
"As president of Sporting CP, I can only be very happy that we have a contract until 2026 with one of the best coaches in the world and that we will continue to make Sporting CP grow."
