Chelsea boss Thomas Tuchel has recalled being coached by Ralf Rangnick ahead of going to Manchester United tomorrow.

Tuchel says the United caretaker manager was a trailblazer at the time.

He said, "The story is told. He was my coach when I was a third division player. He told us some stuff these days that we had never heard about. We don't need to follow as a defender, we don't need to follow our striker when he goes to the toilet. That common sense at this time, that you would just follow him around for 90 minutes.

"He told us we can defend in a back four and defend in spaces, and he opened our eyes and brought big success to the little club where we played, and he went straight through and into the first division. On this run, I got injured, and later when he managed Stuttgart, he opened the door for me to the academy. He gave me the chance to make an internship with the under-17s.

"From there, I tried to be the best possible and also, he had his fantastic record in Germany to build up big clubs, to bring clubs to the very highest level and to build clubs from scratch. This is pretty much the story if I want to tell it as short as possible.

"It's nice to see him always. It's tough to play against teams like his. We will maybe have time for a quick chat, five minutes, but contact is not on a daily or weekly basis."
