How big is Rohl's Rangers rebuild this summer?

Danny Rohl joined Rangers in October, with his contract running until the end of the 2027-28 season

It's hard to have much perspective in the immediate aftermath of your first league Old Firm derby defeat. But Danny Rohl has to learn some lessons, and quickly.

The Rangers head coach has been put out of the League Cup, Scottish Cup and now condemned to third place in the Scottish Premiership by his wily old Celtic counterpart Martin O'Neill.

There will be no Champions League qualifier for the Ibrox side after three destructive post-split defeats against Motherwell, Hearts and Celtic.

It begs a series of difficult questions and another long summer of introspection and rebuilding at Ibrox.

But how many times can this keep happening? And will Rohl be there to be part of the latest fresh start - amid reports of interest in Germany?

The question is already being asked on social media feeds, down the pub and across the kitchen table among Rangers folk.

Up until the split, the answer would have been a fairly unequivocal 'yes'.

Rohl inherited a complete mess in October, including a 13-point deficit to Hearts. But, at the beginning of April, Rangers edged to the top of the league on goal difference - with Hearts not playing until the following day.

However, they have won just once in four games since, losing three in a row in the top flight for the first time since 2000. Nowhere near good enough, as the German is the first to concede.

"We had a great position before the split and this is hard to take and we have to improve and develop quick," he told BBC Sport Scotland after the Celtic Park loss.

"We have to learn in these key moments to be clinical and play without mistakes. We will learn from this.

"I will take a lot from the last three games to be prepared the best way possible. I will lead this group and I am clear about what we have to improve."

Former Ibrox midfielder Andy Halliday said it was "only natural for some Rangers fans to have their doubts" over Rohl.

Speaking on the BBC Scottish Football Podcast, he added: "It's the manner of their last two performances, in particular. When Hearts gave them a punch on the nose at Tynecastle, they didn't respond and it was the same after Celtic gave them a one-two inside four minutes.

"He doesn't like questions about mentality but it's no surprise these questions are coming.

"I think there is quality in that squad and, at the moment, Rohl is struggling to get the best out of them."

Rangers can now only finish in third place

Rangers have already spent a relative fortune this season on their squad - in the region of £40m, although a significant amount came back into the club with some high-profile, lucrative departures.

Rohl may bristle when the mentality of his squad is queried, but the way the side buckled when it came to the crunch begs the question of whether there are enough of the right characters in the Ibrox dressing room.

Former Scotland international James McFadden isn't convinced.

"Winning's hard," he said on Sky Sports. "You need to run more, you need to up the intensity. That's the suffering you need. But Rangers drop their levels when they're in front and that's allowing teams in."

His former international colleague - and ex-Rangers player - Kris Boyd agrees.

"Danny Rohl will come under serious questions," Boyd said on Sky Sports. "There is a mentality problem within that group, there is no doubt about it.

"Again, it'll be another rebuild in the summer. How long does it go on for, though? There's a big, big summer for Rangers coming up and I'm fed up saying it."
