Newcastle boss Alan Pardew has appointed John Carver as his assistant at St James' Park.
The 46-year-old, who fulfilled the same role when the late Sir Bobby Robson was in charge of the Magpies, has signed a contract until the end of the season.
Pardew told the club's official website: "I'm delighted to be bringing John on board. He has an excellent track record as a coach and of course knows this club very well."
After leaving St James' Park following Robson's sacking in 2004, Carver worked under Kevin Blackwell at Leeds and Luton while he also spent just over a year as manager of Major League Soccer side Toronto FC.
Carver said: "I am proud and honoured to be able to come back once again to my home-town club.
"I have been lucky to be able to work around the world with some excellent people. However, I have always been a fan of this magnificent club and the years I spent working here were some of the happiest of my life.
"I am looking forward to working with Alan Pardew and building on the recent strides that the club has taken to get back to where we belong, at the top of English football."
Pardew expects the arrangement to be extended at the end of the season.
Pardew added: "It was crucial for me that I brought in an assistant who I knew would work well with the current coaching team we have here.
"We've got a good solid set-up with some excellent staff and maintaining that stability is very important to me. John fitted the bill perfectly.
"It's a short-term deal at the moment in order that I can get to know John better and it gives us both the chance to see how the next four months pan out working together.
"That said, I'm very confident he'll be a great addition to our coaching staff and hopefully, if things go well, we can make it a longer-term appointment come the summer."
