So I am really pleased that he will take charge of the team for the 100th time in the SPFL League One game against Arbroath at Ibrox tomorrow.
And I am also happy that he will be able to play all of his new signings for the first time in a competitive match when he reaches this landmark.
I think we will see Ally go with two strikers up front. He has an exciting team now who are good from midfield to the front.
They are also strong defensively now he can play Bilel Mohsni at centre-half, Ricky Foster at right-back and Lee Wallace at left-back.
With the likes of Cammy Bell, Jon Daly, Nicky Law and Arnold Peralta in the starting line-up this will now be an SPFL Premiership side.
They also have a current Scotland international in Wallace in their ranks. I was delighted to see him come on against Macedonia in midweek.
He did what he has been doing for weeks in the World Cup qualifier too. He got the ball and he bombed forward. He could have scored at the death.
Fair play to Gordon Strachan for drafting him into the squad and for playing him. It shows that if you are good enough you will get a chance no matter where you play.
The key word for the team from now on will be attitude. If their attitude is right then they will continue to win games.
One key thing, though, is that there is now a strong squad at Ibrox. If anybody allows their standards to drop then somebody will take their place.
But I expect the team to play well. The last time McCoist played all of his summer acquisitions was in the friendly against Newcastle at Ibrox.
The visitors fielded virtually a full-strength team and they were outplayed for most of the game.
People may say that Rangers are only playing in the third tier and they should be dominant.
But that is a bit of a non- argument for me. They can only play in the league they are in.
