Gordon was at fault for one of the three goals Inter scored at Celtic Park in the Europa League, with John Guidetti's late equaliser ensuring Celtic still came out of the game with a 3-3 draw.
The Bhoys goalkeeper, though, has built up a strong rapport with supporters after producing several match-winning performances already this season.
As such, Celtic fans chanted in support of Gordon in the wake of his mistake. Now, the 32-year-old has thanked supporters for that response - and apologised for his error.
“Everyone has made an error at some point in their career and as players we know how that feels, and they responded really well by coming back and getting another goal, as did the fans," Gordon said.
“It was a great gesture from them. I’m sorry that I made them do it but at the same time it did spur me on to come out in the second half and not concede."
Meanwhile, Leigh Griffiths also spoke about his side's rapport with supporters, discussing boss Ronny Deila's 'Ronny Roar.'
The forward was speaking ahead of today's Scottish Premiership clash with Hamilton Academical. After that comes the second leg at Inter...
“He must have done that back in Norway when he won games and the boys never knew about it but the boys love it now and it’s just a bit of banter,” Griffiths is quoted as saying by the Celtic site.
“The fans love it and as long as we keep winning he will keep doing it. You always need to have that closeness between the fans, the players, manager and everyone associated with the club.”
Celtic currently sit top of the table and are also into the Scottish League Cup final and Scottish Cup quarter-finals.
A win at Inter in the Europa League, meanwhile, would secure progression to the last 16. A draw, however, would not be good enough unless it was 3-3 (which would take it to extra-time) or higher in terms of the number of goals.
