The 63-year-old German will take charge of Manchester United until the end of the season before moving into an upstairs role after replacing the sacked Ole Gunnar Solskjaer
The latter role is arguably just as noteworthy as his imminent presence in the Old Trafford hot-seat, given the club have been lacking direction from the top of the hierarchy throughout the post- Sir Alex Ferguson era.
Rangnick also has success as a director of football under his belt after taking on the role for both Red Bull Salzburg and RB Leipzig from 2012 onwards.
Rangnick said: “I am excited to be joining Manchester United and focused on making this a successful season for the club.
“The squad is full of talent and has a great balance of youth and experience. All my efforts for the next six months will be on helping these players fulfil their potential, both individually and, most importantly, as a team.
“Beyond that, I look forward to supporting the club’s longer-term goals on a consultancy basis.”
Often dubbed the ‘godfather of German football’, Rangnick’s playing style is similar to that of Jurgen Klopp’s at Liverpool – both placing a huge emphasis on gegenpressing.
His unbelievable eye for talent has seen his former sides sign the likes of Sadio Mane, Joshua Kimmich and Timo Werner under his guidance.
His arrival comes after former United midfielder Michael Carrick took the the team for the club’s last two games, earning a 2-0 Champions League victory at Villarreal and then following that up with a 1-1 draw against Chelsea at Stamford Bridge on Sunday.
Rangnick has been negotiating the terms of this deal with United’s vice-chairman Ed Woodward, and watched the Chelsea draw in Germany having returned from a trip to England last week.
After initially rejecting the club’s first proposal, an agreement was struck ahead of United facing Arsenal in the Premier League on Thursday.
As United currently languish as low as eighth in the Premier League table, Rangnick has very little time to adapt to the new challenges posed by his first spell in English football.
Regarded as a mentor by some of the best coaches currently in the game, including Bayern Munich boss Julian Nagelsmann, Rangnick’s style of play could see a number of United stars who featured regularly under the old regime now exiled.
A title tilt could be too much of an ask given the festive period of fixtures is already nearly upon us, but Rangnick will be expected to secure a top-four finish at the very least come the end of his tenure.
Speculation linking Paris Saint-Germain manager Mauricio Pochettino with the role on a permanent basis remains rife, though Rangnick’s move into an upstairs role could potentially see the pair work together.
