Santiago Solari has signed a three-year contract to remain Real Madrid manager through the 2020-21 season.
Named interim boss after Julen Lopetegui's sacking, Solari has guided Madrid to four wins from four games in charge thus far.
As Madrid's search for a permanent boss from outside the club failed to bear fruit, Solari has impressed by restoring an air of calm to the dressing room following a tumultuous period under Lopetegui.
The Argentine manager has now signed a contract ensuring he and his staff will remain in charge at Santiago Bernabeu for the rest of the current season, and two more subsequent campaigns after that.
Madrid's search for a new manager initially focused on former Chelsea boss Antonio Conte, but the Italian eventually ruled himself out of the running until at least the summer.
In the meantime Solari, who had previously been in charge of Madrid's reserve side, began achieving results that his predecessor had failed to accomplish.
"The truth is that we are very happy with him," Madrid director Emilio Butragueno told Movistar+ after the win at Celta.
"There is no doubt that he came at a very particular moment and has been able to achieve very good results."
The win at Celta gave Solari four wins from four games in charge, with 15 goals scored and just two conceded.
Those four victories have come in three different competitions, with three of them coming away from home.
Solari has also been able to more successfully integrate new faces like Thibaut Courtois, Vinicius Jr, Alvaro Odriozola and Sergio Reguilon into the side.
"This team has nothing to do with [Lopetegui's side]," a Madrid source told Goal .
Armed with a new deal, Solari will look to keep Madrid's run going against Eibar on November 24.
