Aubameyang played under Tuchel at Borussia Dortmund and has previously heaped praise on his former boss.
"I can't deny his talent. He's someone a bit crazy, a little like me."
He added: "You could say that his style is a bit like that of Guardiola. In any case, they play with the same spirit.
"He likes to keep the ball with a style of play that likes to see the ball move forward, no matter what happens.
"I think he's got the stuff. Now, it'll be up to him to prove it."
