Ralf Rangnick has had a "big influence" on Chelsea head coach Thomas Tuchel's managing career, according to the German.
On Thursday afternoon, reports surfaced that the 63-year-old is set to take over as caretaker manager of Manchester United following the Blues' match against the Red Devils on Sunday.
Tuchel began his coaching career as a youth coach at Stuttgart, where he was appointed by his compatriot Rangnick.
When asked about Rangnick's possible presence at Old Trafford, Tuchel could not hide his respect for someone who, he claims, persuaded him to stay in football when his playing days ended prematurely.
Speaking to reporters at a press conference, Tuchel said: "He helped me a lot because he was my coach and then he was one of the main figures who convinced me to try coaching. He had a huge influence on all of us at this time.
"He showed us that it is not necessary to follow everyone to the toilet in football games because that was the belief at the time. Defenders follow their strikers wherever they go, and he showed us that it is possible to defend in a zone."
Rangnick will be unable to secure a work permit before Saturday's match at Stamford Bridge, but it is reported he will be on the touchline for the Red Devils against Arsenal on Thursday.
