Rudiger has less than a year remaining on his contract at Stamford Bridge and will be free to sign a pre-contract agreement with a foreign club from January.
The former Stuttgart defender is still negotiating with the Chelsea hierarchy on a new deal but an agreement is yet to be reached.
Rudiger has become a pivotal part of the Chelsea set up since Tuchel took over from Frank Lampard in January, having become a bit-part player under the Englishman.
The 28-year-old Germany international played a key role in Chelsea winning the Champions League and UEFA Super Cup as well as their bright start to the 2021/2022 season.
Tuchel is confident that an agreement will soon be reached between Rudiger’s camp and the club.
"I hope that they find a solution but it's not only between coaches and players," he explained ahead of Chelsea’s trip to Spurs this weekend.
"It's between the club and the player's agent.
"He plays excellent for a long time - very consistent [and] at a very high level. I feel him very calm, very focused and it's obviously not a distraction for him.
"So give things time - sometimes it needs a bit longer, sometimes things get very fast. There's no news from my side."
Tuchel added: "I think Toni feels very, very good at Chelsea. He feels respect from his team-mates, he feels the importance he has in the team. It's well deserved because he delivers.
"He feels the love from the supporters. He plays in the strongest league in Europe and in a big club, so not many reasons to change. But it's in good hands. I'm calm and relaxed - whatever has to happen will happen."
