The RB Leipzig forward ended his loan spell at Monaco to join the Championship title contenders.
And Augustin admits the presence of Marcelo Bielsa made it an easy decision.
He declared: "First of all for the coach. Everyone knows him in the football world, he's a real big tactician.
"I didn't have to think long when Leeds wanted me and that he wanted me to come.
"I'm going to bring my football while I'm learning with him and helping the team while doing that."
On Leeds, Augustin added: "It's a historical club in England. It has a big objective this season to go back to the Premier League.
"I know it has been 16 years since they were in the Premier League, so of course the project already excited me.
"It's an exciting project for the players, for the city and for the fans.
"I know it's a big club in England, there are a lot of fans at every game and they want to go back to the Premier League.
"I've played in different leagues and I've never been in England. I know, whether it be in the Championship or the Premier League, I wanted to come here and play here."
