It looks increasingly likely that the 46-year-old will become the successor to Pedro Caixinha after he met with Aberdeen chairman Stewart Milne on Wednesday afternoon. This followed a refusal by the Pittodrie club to allow their manager to speak with the Ibrox hierarchy.
Writing in his column for the Scottish Sun, Boyd insisted it was a “fact” that McInnes will be going to a better football club.
The Kilmarnock striker, who played for Rangers for five-and-a-half years across two spells, pointed to the ongoing situation regarding Aberdeen’s new stadium and training ground for reasons as to why McInnes should leave.
He wrote: “Aberdeen have no one to blame but themselves.
“When Derek McInnes becomes Rangers manager — and that will now happen — there’s no point in Stewart Milne or anyone else at Pittodrie moaning about it.
“Del did his job by rejuvenating the city, let alone the football club. He won them silverware and brought a level of success they hadn’t enjoyed for longer than anyone could remember.
“But for four years he kept getting told there would be a new training ground and stadium built... and he’s still waiting.
“I’m just not having this idea that Del is guilty of letting Aberdeen down. For me, it’s the other way around.
“He’s on the verge of leaving Aberdeen for Rangers because it’s a bigger and better club. That’s just a fact.”
