The two former Bhoys strikers faced off against each other as Omonia of Cyprus faced Danish outfit Brondby.
Though Celtic weren't playing on Thursday night, there was no shortage of former Bhoys players on show in the Europa League for Hoops fans to keep their eyes on.
And one match in particular would have been a great watch for anyone interested in players that once plied their trade at Celtic Park, as Cypriot side Omonia took on Danish outfit Brondby in the Europa League qualifiers.
With the fixture goalless from the first game, the second leg remained a tight contest as both teams scored twice, leaving visitors Brondy going through on away goals.
But that in itself would be of little interest to the Celtic faithful, what was noteworthy was that between them, the two former Bhoys players grabbed all the goals.
Giant Irish striker Cillian Sheridan, who played his first senior football at the club as a youngster in 2006, grabbed both strikes for the home side, while Teemu Pukki, who left Glasgow permanently only this summer after a difficult spell in Scotland, scored the two away goals that would ensure the famous Danish side's qualification to the next round.
If only they could have displayed that kind of form at Parkhead, maybe they would have had a longer career with the Scottish giants.
