Arsenal are reportedly the latest Premier League club to register an interest in Sporting Lisbon youngster Nuno Mendes.
The recently-turned 18-year-old has already been linked with Manchester United and Liverpool after making nine top-flight appearances for Sporting last season.
Predominantly used as a left wing-back, Mendes is said to have also caught the eye of AC Milan, who are rumoured to have had a £13.5m bid rejected earlier this summer.
Portuguese outlet O Jogo reports that Arsenal are now ready to make an approach for the Sporting academy player, but they may have to pay around £40m for his services.
Mendes recently signed a five-year deal at the Estadio Jose Alvalade and the Primeira Liga outfit are under no pressure to sell.
