Chelsea and Manchester United are reportedly both keeping an eye on the process of Cagliari defender Sebastian Walukiewicz ahead of possible bids.
The 20-year-old joined Cagliari from Polish side Pogon Szczecin in 2019 and has made 21 appearances for the Italian club in all competitions since his arrival.
The centre-back has played every minute of his team's five Serie A matches this season, meanwhile, having secured a starting role for Eusebio Di Francesco's side.
According to 90min, both Chelsea and Man United scouted Walukiewicz while in action for Poland against Italy in the UEFA Nations League earlier this month.
The report claims that scouts, who were also present from Atletico Madrid, Inter Milan, Lazio and Borussia Dortmund, were especially impressed by the central defender's aerial ability.
Walukiewicz still has two and a half years remaining on his current deal with Cagliari, while the Italian side also have the option of extending the agreement by a further 12 months.
