McGeady has been out of action for several weeks, initially with a calf problem that has now aggravated a weakness in his knee.
McGeady said: "It's frustrating because I feel as though my season has hardly started and I've not really had a run of games.
"It's not my calf anymore. It's my knee. I trained last Tuesday but I missed the last few days because I couldn't really run properly.
"It's a sort of tendinitis. I think you can get an operation but I would not want to resort to that because it's a big part of the season for us.
"I'll try to get through it with rest and hopefully it won't trouble me.
Whilst I am sure that I am not alone in hoping that Aiden is available sooner rather than later I certain would not wish him to cause himself any long term problems. This opinion appears to be shared by other, more learned and experienced persons:
"I was talking to Neil Lennon and he was saying he had the same thing and I'd have to watch because he needed surgery.
"It's been tough not playing with the team doing so well. I wanted to capitalise this season and take myself on to the next level but it's been a bit stop-start.
Aiden however was quick to state that he would play tonight if his services were required:
"If I'm in the team I'll be looking to play well to show the manager I'm worthy of a regular place." He said. He was also quick to point out that Celtic can expect a tough game in Denmark, regardless of the opposition.
He said: "It's a Champions League game and Aalborg are here on merit. They have done better away than we have and scored more goals.
"They went to Villarreal and scored three and that's good going because we didn't create much there.
"But we've seen Aalborg at first hand at Celtic Park and although we didn't play well enough ourselves on that night, I think we saw enough to believe we have a better team and this is a game we should go out and win. It is obviously a game we can win.
"At home, the fans were expecting us to win. There was pressure on us and we didn't really handle it too well.
"We still came away with a point but you want to get off to a great start and we've not done that in the last few years.
"But I don't think Aalborg created a lot of chances and without going over the top I thought we should have gone on and won.
"If Aalborg think they have a good chance of beating us at home they may attack and we could exploit spaces.
"I'm sure their two full-backs were attacking in the first game and we could take advantage on the counterattack."
Aiden was also grounded when discussing Celtics chances of progressing to the latter stages of club Footballs premier competition. He said: "We still have a chance of qualifying if things go our way in the other game so we need to win and hope.
"Wins for us and Manchester United would be the dream scenario but we just need to wait and see what happens.
"We have to look after ourselves and maybe United can do us a favour in Villarreal.
"We'll try to win first and foremost. You never like losing and it has become a habit away from home. It is not a good habit.
"I was in squads at 17 years old but never stripped. AC Milan away when we lost 3-1 was my first as sub.
"I've been here for the majority of the games but a lot of the players have not and the manager has spoken about that.
"We want to win away from home and get some points because one out of 51 is not good enough."
Yours in Celtic
