Austria has named a new boss.
At the end of the season, Rangnick will continue to work as a consultant for United.
He said he was looking forward to helping United become a force again.
The 63-year-old German has signed a two-year deal with Austria and will join them after the season ends in May.
Franco Foda resigned as Austria's head coach in March after they failed to qualify for the World Cup.
The president of the Austrian Football Association said that they were very pleased that they were able to win an expert in international football.
We are all convinced that he is the ideal man and that his vision will advance the national team.
Since November, United have won 10 of their 25 games.
With three games to go, United are five points behind fourth-place Arsenal.
In the summer, ten Hag will become United's fifth permanent manager since Ferguson's retirement.
The head of sports and development at Russian club Lokomotiv Moscow left to join United, having built an impressive coaching reputation in Germany.
He took charge of Ulm and set them on their way to promotion to the top flight.
He won the German Cup and reached the semifinals of the European Championship.
It is an honor for me to be the Austria manager.
The prospect of contesting the European Championships in Germany with a young team hungry for success fills me with great anticipation.
Simon Stone is a reporter for the British Broadcasting Corporation.
He wanted to be free to take on other roles after his two-year consultant role at United ends.
It would be difficult if he was at another club. The appeal of the international game is obvious with so many players from the Red Bull franchise in the Austria squad.
The two-year, six-day-a-month consultant role he has agreed to with United is something he is committed to. If they don't need his services, he will step away, so it's up to them how much they tap into him.
It would not be a good move. If United are to recover from this miserable campaign, his input is crucial.
