The Premier League's biggest clubs are eyeing Sporting Lisbon centre-back Eduardo Quaresma.
Goal says the Portugal Under-19 international has also attracted interest from several European heavyweights.
Quaresma arrived at Sporting Lisbon in 2011 from G.D. Fabril's academy and has risen through the ranks over the past nine years.
The 18-year-old has been playing for Sporting's Under-23 squad but the arrival of manager Ruben Amorim has seen him join the first team.
Quaresma made his senior debut on June 4 during a 2-2 draw with Vitoria and he's been a regular ever since - making eight appearances.
And his exploits have attracted the attention of some major clubs.
Manchester United, Chelsea, Liverpool, Juventus, Inter and Atletico Madrid have all been linked with the talented right-sided central defender.
Ole Gunnar Solskjaer's United could have an advantage with Quaresma signed to Unique Sports Management - the same agency who represent Aaron Wan-Bissaka and Axel Tuanzebe.
