Some of the Premier League's biggest clubs are preparing to table offers for 18-year-old Charlton Athletic defender Ezri Konsa in the January transfer window, according to reports.
The Daily Mirror says scouts from Arsenal, Liverpool and Manchester United have been at Charlton's games this season to watch Konsa.
Chelsea and Manchester City have also been linked with the player, who has made seven appearances for Charlton in League One this season.
The Mirror says numerous scouts from the Premier League's elite clubs watched Charlton's 1-1 draw with Oldham Athletic on 27 September to run the rule over Konsa, who won the Man of the Match award for the game.
He is rated by the Addicks to be as bright a prospect as Joe Gomez, who joined Liverpool on a five-year deal for a fee of £3.5m ($4.5m) last year.
Konsa came through the youth ranks at Charlton and signed a contract in December last year that runs until 2019, according to the Mirror.
Meanwhile, United manager Jose Mourinho said he was pleased with his team's 1-0 win in a "difficult" game against Zorya Luhansk in the Europa League.
Zlatan Ibrahimovic converted Wayne Rooney's mis-directed shot in the 69th minute at Old Trafford to give the Red Devils their first win in Europe this season.
"It was difficult. We had our chances in the first half, we could obviously score and have a different match, but we didn't," Mourinho told United's official website.
"They stayed very organised with lots of people behind the ball. The danger was hidden but they were always ready to do something on the counter-attack.
"The game was difficult but it was important to win. We have another game on Sunday [against Stoke City] and that's now the most important one."
United are in third place in Group A in the Europa League, one point behind leaders Fenerbahce.
