The Ibrox club named the 36-year-old German as Russell Martin’s successor.

Steven Gerrard and Kevin Muscat were both in the running for the role at different stages, but Rohl impressed during the recruitment process.

Rohl’s appeal lies in his coaching skills and experience at clubs with high expectations.

However, some have expressed concern over his lack of experience as a head coach and his similarity in profile to Martin.

Former club captain Ferguson, who was interim boss last season, has vowed to support the new man in charge.

Speaking on Go Radio, he said: “It’s been a long two weeks for the Rangers fans.

“It looked like Steven Gerrard was coming back, I was quite happy with that.

“The contract negotiations didn’t go well, then Kevin Muscat looked to be getting the job.

“Again, I think that would have been a really good appointment because he’s been a manager for 12 years and he’s doing a fine job in Asia.

“On Sunday night it breaks that Muscat isn’t getting the job and then it’s Danny Rohl – who last week ruled himself out.

“So it’s been a bit of a crazy 15 or 16 days for the Rangers fans.

“Now they’ve got a new manager in place, I’ve seen that he likes to set high standards… his high standards have got to be winning games of football as quickly as possible.

“If he does that, he’ll certainly get the support of the Rangers supporters.”

Rangers are currently sitting sixth in the Premiership, with only one win from eight after drawing with Dundee United at the weekend.

However, Ferguson insists that he is not concerned about their league position at this stage and believes a title race could still be on the cards.

He said: “No, not at this stage.

“Eight games.

“30 games to go.

“90 points to play for.

“There’s still a lot of football.

“They are still in four competitions.

“Hopefully he can come in and certainly make a difference.”

Rohl is set to face his first challenge as manager on Thursday night in a game against Brann.

Ferguson believes that if Rohl can start winning games quickly, he will gain the support of the Rangers fans.

He added: “One thing I’ll be doing is getting right behind him.”

Ferguson also commented on the upcoming match between Celtic and Hearts, saying: “The best result for Rangers is a draw at Tynecastle.

“Rangers beat Kilmarnock and then it’s back on.

“It can change so quickly.

“And the big thing for Derek McInnes and Hearts is that he needs to keep his best players injury-free.”
