Jurgen Klopp is widely expected to formally take over as the new head coach of the German men's national football team, with the German Football Association (DFB) calling a press conference for Friday.

Klopp, famed for his success during stints as coach at Borussia Dortmund and especially Liverpool, has been in talks with the DFB about trying to lead Germany -- long a football powerhouse -- back to prominence.

On Thursday, the DFB invited the media to a press conference on Friday morning at 11am at its Frankfurt headquarters, without specifying the topic.

That is because the DFB's governing bodies have not yet met to formally approve the deal with Klopp, according to reports from AFP's sports subsidiary SID.

Klopp, 59, is among the most decorated football coaches of his generation and is expected to sign a contract with Germany that runs until 2030, the date of the next World Cup.
