If Rudiger is allowed to depart west London, the decision will likely irk Tuchel, who has a history of clashing with club hierarchies.
Tuchel came to blows with bosses at Borussia Dortmund in 2017 and did so again at Paris Saint-Germain last summer.
Chelsea chiefs will not want to pick fights with Tuchel after his impressive start to life at Stamford Bridge.
But if they do, they would be repeating the same mistake they made with Antonio Conte before the Italian departed the club three years ago.
“I don’t know if my ambition is shared by the club,” Conte hissed four months before he was shown the exit door.
