Telecommunications company NOS has extended its title sponsorship of the Primeira Liga, the top tier of club football in Portugal.
The new agreement will run until the end of the 2020-21 season and will see the league continue to be officially known as Liga NOS.
NOS has sponsored the league since February 2015. The league was previously co-title sponsored by beer company Sagres and ZON Multimedia.
NOS administrator Ana Paula Marques said: “With state-of-the-art technology and a multi-platform approach to delivering sports content, we will continue to build an even more interactive, exciting and ever closer Liga NOS.”
