Zinedine Zidane held a news conference to announce he was leaving Real Madrid in May 2018
Zinedine Zidane is set to return as Real Madrid manager just 10 months after leaving the Spanish giants, according to European football expert Guillem Balague.
The Frenchman will replace Santiago Solari, who was in charge for less than five months.
Former Real midfielder Zidane, 46, left in May after leading the club to a third straight Champions League trophy.
Real are currently third in La Liga, 12 points behind leaders Barcelona.
Solari is set to be sacked after a 4-1 win over Real Valladolid on Sunday - which followed a shock Champions League exit to Ajax.
That 4-1 home defeat and 5-3 aggregate loss to the Dutch side was the final straw for Real president Florentino Perez.
The defeat by Ajax followed two consecutive defeats by Barcelona in El Clasico - a 1-0 loss in La Liga and a 3-0 thrashing in the Copa del Rey.
Zidane stepped down following the Champions League final victory over Liverpool, and Julen Lopetegui was hired as his successor just before the World Cup where he had been due to lead Spain, who promptly sacked him.
Four and a half months later it was Real's turn to fire him.
Reserve-team boss Solari came in as caretaker before being given a contract to 2021 on 13 November.
What job faces Zidane at Real?
Despite returning less than a year after he left the club, Zidane faces a rebuilding job at Real Madrid after their Champions League dynasty came to a remarkable, humiliating end last week.
They have not adequately replaced Cristiano Ronaldo, who left for Juventus in the summer, with Karim Benzema the only Real player to reach double figures in La Liga (13). He has scored 22 goals in all competitions, with Gareth Bale on 13 and Sergio Ramos on 11.
None of those players have certain futures at Real, with captain Ramos, who has been at Real for 14 years, reportedly falling out with president Perez. Wales forward Bale is expected to leave because of a fractious relationship with the club's fans - who have booed him recently - and players.
Other stalwarts of recent glory like Marcelo and Toni Kroos have struggled too.
More than 300,000 Real Madrid fans voted on Marca's website on whether they should keep Gareth Bale. Only 8% said yesAnalysis

Zinedine Zidane will be in charge of Real Madrid from today and will probably take the team training on Tuesday.
There will be a board meeting today and that will confirm the sacking of Solari and also the appointment of Zidane.
Of course that may mean difficulties for Gareth Bale, who did not get on very well with Zidane.
Sergio Ramos will have his authority reinforced and Zidane also wants the likes of Eden Hazard and perhaps even Christian Eriksen to add to the side.
He will be given all the sporting authority and all the things he suggested in the summer that Florentino Perez did not want to do - most of them will be done now.
Zidane is coming in with the idea of not just managing the side but also managing the decisions for the first team.
