Arsenal are reportedly keeping a close eye on Polish teenager Sebastian Walukiewicz after being identified by head of recruitment Sven Mislintat.
The 18-year-old, who currently plays in his homeland for Pogon Szczecin, is said to be viewed as a long-term option in the centre of Unai Emery's back four.
Football.London claims that Walukiewicz has been watched up close by Arsenal scouts this season, having only made his breakthrough into the first team towards the end of the last campaign.
A number of other clubs have been tipped to make a move for the former Legia Warsaw defender, however, including Spanish champions Barcelona and arch-rivals Espanyol.
Walukiewicz has featured in 13 of Pogon's 15 league matches this season, with all but one of those coming as starts.
