The on-loan Manchester City man starred as the Bhoys cruised to a 3-0 win against Lincoln Red Imps.
Celtic's decision not to field Patrick Roberts in last week's Gibraltarian humiliation was made to look all the more bizarre by the winger's dazzling display in Tuesday's return leg.
Having already teed up Leigh Giffiths to put the Bhoys two up on the night and into an aggregate lead against Lincoln Red Imps, Roberts struck a sublime third to remove any doubt over his side's progression to the Champions League's third qualifying round.
Griffiths smashes in Celtic's second
Cutting in off the right flank, the on-loan Manchester City man played a neat one-two with Callum McGregor and swept a left-foot strike into the far corner, to cap a run of three goals in twice as many first half minutes.
Roberts caps a fine Celtic
The Celtic supporters were left purring at Roberts' performance, with some going so far as to liken him to five time Ballon d'Or winner Lionel Messi.
However, if he scores more goals like that one, he may have to get used to that particular comparison - especially after Pep Guardiola's arrival at the 19-year-old's parent club.
Messi: The old Patrick Roberts?

What a player @patrick7roberts is! Shame we probably won't have him here next season. City have some real talent on their hands.— Murray Macdonald (@DMMacdonald96) 21 July 2016
Im glad Patrick Roberts is only on loan as we'd probably have sold him by now.At least we get another season to see him.— J.P Mullen (@Buzzbomb11) 21 July 2016
