Potential incoming Manchester United boss, Ralf Rangnick, rejected a similar approach from Chelsea last season.
The German veteran is one of the most respected coaches and football consultants in Europe.
Currently working with Zenit St. Petersburg, Rangnick is set to take over at United as interim boss, per David Ornstien and other reliable British and European media sources.
In an interview with The Times, Rangnick stated he was not eager to become Chelsea interim boss.
He said: “‘I said: ‘I would like to come and work with you, but I can’t do it for four months.
“I’m not an interim coach.
“To the media and players you would be the ‘four-month manager’, a lame duck, from day one.”
He added: “If you watch Chelsea now you see a mutual plan for when they have the ball or the other team have the ball.
“Thomas [Tuchel – who Chelsea went on to appoint] is tactically on a very sophisticated level.
“Zsolt Low [Tuchel’s assistant] was my player and assistant coach at Leipzig and plays a vital role in his staff.
“And you can see from the way he interacts with players Thomas also has great leadership skills.
“Appointing him was a top solution. I can only congratulate Thomas and Chelsea for the choice.”
