There were doubts Mount would start under the new coach, having been a favourite of previous manager Frank Lampard.
But the 22-year-old has featured regularly under Tuchel in a number of different positions, which he describes as a 'roller-coaster' experience.
"It has been a bit of a roller-coaster over the last couple of months but it has been a valuable experience; I have learned a lot after being captain for the first time," Mount said.
"I've played five positions in a match, not three! I changed a couple more but all good experiences for me to learn. I'm versatile and I can change positions. That's what the modern game is about."
Mount's performances saw him called up for England's World Cup qualifiers.
On returning to the England camp, Mount added: "Coming into the international break, we're all excited, buzzing to be back together. We're ready to be down to business and play the games. It feels like yesterday that I made my debut at Wembley and it has gone so quick.
"You gain confidence and learn more in each camp. You want to keep getting better and better; that's the main thing. That's both personally and as a group. We are on the right track. It starts with these World Cup qualifiers and the game tomorrow."
