Rangers and Celtic are due to meet in the Scottish Cup in April.
The Bhoys have been guilty of stock piling players in certain positions, with the club clearly having too many attacking midfielders.
And Boyd believes that Rangers actually have a stronger side than their rivals now, because of Ronny Deila’s erratic recruitment policy.
“It’s a difficult one to say who is the stronger side from one to 11,” Boyd said. “I’d say Rangers for the way they’ve gone about everything and the fact they’ve not changed the way they’ve played.
"Rangers players are turning up knowing who’s going to play because they’ve got a tight-knit unit which can go a long way. Celtic must have about 100 players sitting in there. For a long time it seems like they’ve been saving them up.
“They’ve signed so many players and not used them for some reason. For me that brings problems in itself because you have a number of players not really doing anything apart from training. Most of the Rangers players are going to training now knowing if they are playing at the weekend whereas a lot of the Celtic boys know they aren’t going to play which isn’t easy.
"I’ve been there myself when you know you aren’t getting a game at the end of the week and it festers away at you. You can become a negative influence in the whole group. If you have X amount of them not playing, it can harm you.”
Celtic's bloated squad has struggled to meet expectations throughout the campaign so far, and they have under performed.
The Bhoys crashed out of Europe early, and although they look set to win the Scottish Premiership, they have been far from convincing.
Celtic are currently only four points clear of their nearest challengers, Aberdeen, and their form is not particularly encouraging.
Ronny Deila is under serious pressure at Parkhead, and Rangers will have the opportunity to test themselves against the Norwegian’s side in April.
Rangers and Celtic have been drawn against each other in the Scottish Cup semi final, with Deila’s side under serious pressure to make sure they progress.
