Rafael Benitez has been named as Newcastle’s new manager, following the sacking of Steve McClaren.
The former Liverpool, Chelsea, Real Madrid, Inter Milan and Valencia boss takes over with the Magpies a point from safety with 10 games left.
The Spaniard, 55, has signed a three-year contract, which is understood to contain a break clause should Newcastle be relegated at the end of the season.
“C’mon Toon Army. The club and I need your total involvement,” he said.
Benitez was sacked in January after seven months as Real Madrid boss.
He spent six years as Liverpool manager, winning the Champions League in 2005. He also had an interim spell with Chelsea, guiding the Blues to Europa League success in 2013.
“I have the pleasure to confirm I have committed to a legendary English club, with the massive challenge of remaining part of the Premier League,” said Benitez, who has brought in coaches Fabio Pecchia, Francisco de Miguel Moreno and Antonio Gomez Perez.
“It will be a challenge not just for me and my staff but for the players, the club and the fans.
“All of us must push together in the same direction and with the same target in mind. This is the reason why I’m going to ask for your total support to successfully complete this task.”
The former Liverpool manager, whose family still live on the Wirral peninsula in the north west of England, added: “Personally, it means my return to the Premier League, closer to my home and my family. I can’t be happier.”
McClaren was sacked after just nine months in charge.
Under the former England manager’s guidance, Newcastle won just six of 28 Premier League games.
Coaches Paul Simpson, Alessandro Schoenmaker and Steve Black have all left the club.
