Ralf Rangnick has opened the door to taking the technical director's job at Manchester United.

Rangnick was head coach and sporting director at RB Leipzig last year and is now head of sport and development at Red Bull, with responsibility for teams in New York and Sao Paulo.

"I am happy where I am but if any club wanted to speak to me, the question would have to be: 'Can I be somebody who can influence areas of development across the whole club?' Otherwise you are only getting half of what I am capable of," he told the Guardian .

"If, after that, you can work together in a trustworthy and respectful way, then you are more likely to be successful."

United are trying to change their approach from the Sir Alex Ferguson era, when the domineering Scot was a head coach, manager and director of football rolled into one.

“It's always difficult to follow someone like Sir Alex Ferguson, who was so successful and in place for a long time – and that's even harder if you are often changing coaches," he said.

“With every coaching change, the identity changes and this is reflected in the sporting development. You can look at the money that team has had available in the last five years and say there has been an underperformance."
