Players have already had to adapt to Rangnick switching training sessions from a traditional morning slot to the afternoon, a change that was met with some resistance.

The interim boss is renowned for his analytical approach and meticulous attention to detail, leaving nothing to chance to bring out the best in his teams.

The German puts a heavy emphasis on video analysis, and footage of player performances is sent to them by email.

He and his coaching staff tailor clips to each player, with advice and pointers on where they can improve.

Rangnick’s move echoes the approach of former United boss Louis van Gaal, who used to send out emails detailing mistakes, with video clips showing the errors.

The players were so enraged, they started deleting the emails as soon as they landed in their inboxes. Van Gaal (above) suspected that was the case so had a tracker installed which allowed him to check if the emails were opened and for how long.

Rangnick is keen to make Leipzig midfielder Amadou Haidara his first signing, but United will not sanction arrivals unless players are sold or loaned out.

The club are also said to be reluctant to do business in this transfer window as new recruits might not be wanted by their next permanent boss, with Rangnick stepping into a consultancy role at the end of the season.

Mauricio Pochettino and Erik ten Hag are the candidates, with United likely to wait until the summer for their new boss to give his approval to any signings.
