Barcelona are tracking 18-year-old Estoril central defender Jordan Arnoldin, according to Portuguese newspaper Record.
Scouts from the Catalan club were present for Estoril’s 4-0 defeat by Porto in the Portuguese league, as they continue to assess the teenager’s performances.
Arnoldin has also attracted interest from Brighton and Lille. However, none of the three clubs has made an official offer to Estoril for the defender.
Arnoldin has played six matches in all competitions this season and has received two yellow cards.
His market value is currently estimated at 300,000 euros by Transfermarkt.
