Allison Langdon is set to become the new Georgie Gardner, Deborah Knight could be the old Sylvia Jeffreys and Karl Stefanovic is being reinvented as... Karl Stefanovic. 

Channel Nine's breakfast and morning television line-up is set for a major overhaul which is tipped to see at least half a dozen network stars change roles.

A new round of musical chairs caused by Karl's sacking from Today co-hosting duties last December will play out in coming weeks as he steps back into that role.

As with any such game, there are not enough chairs for everyone taking part to come out a winner.

Big-name personalities must fall as the search for the right on-air combinations to deliver the ultimate ratings prize continues.

What happens at Today could see familiar faces turn up on Nine's lower profile Weekend Today program, as well as its weekend news broadcasts.

Sonia Kruger's departure from Nine for a return to Channel Seven will leave her chair vacant on Today Extra, which could also be occupied by a Today discard.

Today's terrible ratings in the important breakfast time slot need to be arrested and the solution appears to be Karl and Allison Langdon replacing Deborah and Georgie.

If all these movements seem confusing, Daily Mail Australia has looked at the breakfast TV landscape and put together each piece of the puzzle. 

Karl Stefanovic and Allison Langdon: Hosting a new-look Today show 

Nine chief executive Hugh Marks wants to reinstate Karl at Today in a bid to reverse the show's ever-sliding ratings, according to a report in Tuesday's The Australian.

The Nine-owned Sydney Morning Herald confirmed Karl's return on Friday. 

Karl, 45, will take on the role alongside 60 Minutes reporter and Weekend Today host Allison Langdon, which means Today's current hosts, Georgie Gardner and Deborah Knight, will be redeployed elsewhere.

Deborah joined Georgie at the helm of Today in January, a month after Karl was axed from the program amid a flurry of negative headlines about his personal life.  

The pair has since struggled to gain any traction against Seven's Sunrise, with the Nine show's ratings reaching an all-time low of 155,000 on November 1. This was almost half of Sunrise's 277,000.

In comparison, Today's ratings hovered around 300,000 throughout 2016 and 2017 when Karl was hosting alongside Lisa Wilkinson with Sylvia Jeffreys reading the news.

Rob McKnight, the former executive producer of Studio 10 and editor of industry website TV Blackbox, said the decision to cast Deborah and Georgie was a mistake. 

'They threw a bunch of people together and it just didn't work out,' he said.  

As for whom Karl should co-host Today with, McKnight said 40-year-old Allison would be a perfect fit.

'Chemistry is everything in this game and it was obvious to everyone [Karl's] partnership with Georgie didn't work from the get-go,' he said. 

'Allison Langdon will prove to be a good partner to Karl and will give him a run for his money, but she'll also work very well with him.'
