Giorgos Giakoumakis may have left Celtic in February this year but fans have not forgotten the towering Greek forward. And the headlines of watching current Parkhead star Liam Scales, an ever-emerging presence in Brendan Rodgers' team this campaign, make his full debut for the Republic of Ireland was spoiled by his former Celtic friend with a bullet header at the Aviva stadium to put Greece ahead.
Giakoumakis was the subject of much debate from Hoops fans when he upped sticks for the MLS and Atlanta United in a deal worth around £3.5m to a then Ange Postecoglou.
Many of the Parkhead persuasion reckon the 28-year-old, who is tearing it up stateside with 24 goals in his last 56 appearances for both Atlanta and the Scottish champions, wasn't given the full rub of the green.
And he left Scales staring down at the turf when he latched on to an unstoppable header after just 20 minutes to hit Stephen Kenny's men with a further Euro 2024 qualifying setback.
