Arsenal fans were left raving about Krystian Bielik's performance against Western Sydney Wanderers on Saturday.
The 19-year-old enhanced his reputation as a hugely-promising young player at Arsenal, but first-team chances will be limited for him under Arsene Wenger next season.
ESPN reported in May that the Poland Under-21 international might be available on loan again, after spending time with Birmingham City in the Championship last season.
With Celtic needing a centre-back, should Brendan Rodgers try to get him?
Rodgers is in the market for a defender after Dedryck Boyata was ruled out for three months, leaving him with Jozo Simunivic, Erik Sviatchenko and unproven Kristoffer Ajer.
Bielik is still relatively unproven himself, but a fantastic stint in the Championship during the second half of the 2016-17 campaign has shown that he can certainly handle himself.
The Pole, who can also play in central midfield, needs games and he'd get them at Celtic.
A season with Arsenal's Under-23s wouldn't do a lot for his ongoing development in comparison to a full year in the Scottish Premiership, playing in a successful team.
Rodgers has been linked to a couple of centre-backs - including Steven Caulker, who has off-the-field issues and signing him would be a risk - but bringing in the youngster on loan could be the latest masterstroke by a manager who specialises in them these days.
