The Everton goalkeeper established himself as number one for the Three Lions during Gareth Southgate's reign and revealed that his desire to convince Tuchel of his talents has taken his game to a higher level.
Pickford told reporters: "I think you've got to set your standards, set your stall out again, it's like with football where any new manager (comes in). You might have a good reputation, but they need to see it with their own eyes. I think that's what drives me even more, whether it's a new manager or a new season. I'll always try to improve.
"I'll always push those boundaries to improve. So when the manager came in last March, I knew that. It was not like a trial, but I felt, ‘Right, I need to go and showcase who I am and what I can do to put an impression on the manager.’
"That's what drives me and what pushes me on. Just keep improving, keep being consistent and keep driving those standards for myself to showcase on the pitch.
"If I do everything in training and have that right mentality, the work I do off the pitch, everything coming together, the game itself should be a showcase of how good I am and how good the performances I’m putting in. So that's a consistency I demand on myself, and I feel like I drive myself each and every week."
Pickford has made 82 appearances for England and dreams of reaching the 100 mark, although this ambition pales in comparison with his desire to help the Three Lions lift the World Cup in North America this summer.
He said: "Yeah, the 100 caps is in the back of the mind. There is always those chapters and always those goals. My goal, though, everyone knows what our goal is with England.
"Personally, that's my goal for the next seven weeks - to win, lift that trophy. A lot of hard work, a lot of chapters going through it. That's my goal, but then we'll look at the caps."
