Gus Poyet was today handed the task of dragging Sunderland out of relegation trouble after being named as Paolo Di Canio's successor.
The 45-year-old Uruguayan has signed a two-year deal and will take charge with immediate effect, the club has confirmed.
The former Brighton manager's initial challenge will be to secure a first Barclays Premier League win of the season with the Black Cats currently lying at the foot of the table with just one point from their first seven games, a return which leaves them six adrift of safety.
Poyet's arrival at the Stadium of Light, where he becomes the sixth permanent manager in less than five years - his official title, like that of predecessor Di Canio, will be head coach - was confirmed on Tuesday morning.
Owner Ellis Short, who took more than a fortnight to find the right man, said: "We analysed a wide range of candidates and believe that Gus' track record, experience, commitment and passion make him the right man to take us forward."
"We welcome him to Sunderland."
"The time of Paolo has come to an end and it is time to move forward" - Gus Poyet
The former Chelsea and Tottenham midfielder, who will be joined by staff Mauricio Taricco and Charlie Oatway, has been out of the game since parting company with the Seagulls during the summer on less that friendly terms.
His track record as a manager is limited to his experience with the South Coast club and Sunderland have given him his first chance to work in the English top flight, although he had earlier been part of the coaching set-ups at Swindon, Leeds and Tottenham.
However, his record at Brighton was impressive, having guided them to the League One title at the end of the 2010-11 season and into the Sky Bet Championship play-offs at the end of the last campaign before his untimely departure.
Poyet will be required to work within the system installed by Short after Di Canio's arrival with the Texan businessman determined to continue despite the failings of the Italian's brief and often chaotic reign.
That will mean working under director of football Roberto De Fanti in an attempt to provide the club with long-term future success.
De Fanti and chief scout Valentino Angeloni recruited no fewer than 14 signings during the summer transfer window, several of them ostensibly for the development squad.
However, Di Canio, who was at the helm for only 13 games and 175 days, was still in the process of moulding his new-look squad into a unit when he was relieved of his duties after his relationship with some of his players hit rock-bottom.
Poyet will now take up the baton with the Black Cats at least having shown promising signs of gelling under interim head coach Kevin Ball in recent weeks. The latter will be part of the new management set-up.
Looking ahead to his new role, Poyet said: "The time of Paolo has come to an end and it is time to move forward. We are all different and I don't think it is right to compare people.
"I know a lot about the players at Sunderland, and I know for them it is going to be even more difficult now with another new manager.
"I have to make sure they are comfortable here and we will make sure they are ready and without excuses."
Poyet will inherit a club stranded at the bottom of the table with just one point from their first seven games and already six points adrift of safety.
