Tuchel confirmed that Kante will start their FA Cup clash at Barnsley before praising his impact and the quality his possesses.
"I think N'Golo fits into any manager's plans on the planet," Tuchel told reporters. "I was desperate to have him in my teams [in the past].
"I am so happy to have him back again. We put him on the pitch against Tottenham and he helped everybody on the pitch, which is what he does.
"To see the guy live, to see how he works, how humble he is, the quality he gives to the team. I am so humble to be his coach. He will start tomorrow."
Kante has been plagued by a number of injuries in recent seasons and struggled to get a real run of games going under Frank Lampard last season.
However, Tuchel is not worried about the midfielder's fitness and insists he will still be playing a key role in the Chelsea squad.
"[I am] not concerned about any more injuries because I feel the support and quality of the medical department. We can manage his minutes and workload and take care of him," Tuchel added.
"I am not concerned about his quality. What I see on the pitches here at Cobham is, how can I put it, it's everything I expected and I expected a lot because I am a huge fan of him.
"I can see the input he has on teams. He makes teams better. He has the mentality of a water carrier but on such a high level."
