Spartak's season went into freefall after they lost 3-2 to Celtic in Moscow and last Friday night's 4-2 defeat against Zenit St Petersburg was their third home loss in a row.
Celtic must get a better result than Benfica, who play in Barcelona, to make it into the Champions League knockout rounds.
McGeady (pictured) is certain of a warm welcome before the match. However, he knows that things could change rapidly depending on how the evening develops.
"I'm really looking forward to this game," he admitted.
"I hope the Celtic fans will give me a good reception, but I'm not sure they will.
"Despite everything that has happened, I hope we can still win in Glasgow.
"I was delighted to be playing after a long spell out injured, but the team was upset to lose to Zenit.
"The new coach, Valery Karpin, kept everything the same, really. He didn't change much.
"Our main hope is that the supporters don't desert us. We need them more than ever now."
