Gers won 2-0 on Matchday One away to the Belgians, and followed that up with an excellent home win over Lech Poznan and back-to-back draws with big-spending Benfica .
Victory tomorrow then will guarantee more European football after Christmas, and to be in this position so early, McGregor believes that shows the progression of the side under Steven Gerrard.
He told this morning’s press conference: "Over the three years, there has been a gradual improvement, and that comes with winning games.
"Consistency is keeping on winning, and at this moment in time, that is what we are doing.
"Does it compare with other teams? Potentially, but let's not get carried away - it's still very early and I'll just take it one game at a time.
"Since the Gaffer came in, we have been very good in Europe. Obviously, when the group was drawn, it was a difficult group - we knew that, and we could be in a better position.
"But we can take the positives out it - we are in a decent position and Standard Liege will be difficult opponents which they showed in the first game.
"So we will do our due diligence and try and go out and do our best as we do in every game.
"Every season, you want to do better than the last. I think when the group was made, to have put ourselves in this position, you would have taken it.
"The job is certainly not done yet, but progression year-on-year is probably trying to do better than last year, whether that is possible or not.
"I think first of all, we need to concentrate on tomorrow night, get a good result and then take things from there."
If he plays tomorrow, McGregor will break Barry Ferguson’s European appearances record for Rangers.
It’s an incredible achievement for a man who shows no sign of stopping, and he continued:
"At the moment, we are just concentrating on the game but it will probably kick-in later in life where I realise what an achievement it is.
"Obviously, it is a very proud one, and just to be a part of it will be unbelievable."
