Famalicao midfielder Gustavo Assuncao is attracting major Premier League interest.
AS says Manchester United are keeping an eye on Assuncao.
The 20-year-old has established himself as a mainstay in the Famalicao midfield since joining the club in the summer of 2019.
United will face competition from the likes of Wolves and Everton for Assuncao, as well as Sevilla and Nice.
An offer of around £23million could tempt Famalicao into selling.
The Brazilian has 46 appearances and two assists to his name during his time in Portugal.
