Speaking ahead of a clash between Leverkusen and Dortmund last year, Havertz told Kicker: “Sancho and Haaland don’t play too badly, but he’s the best player at Dortmund at the moment.”
Gotze has also previously spoken of his admiration for Brandt.
After his Germany team-mate joined Dortmund, Gotze said: “I think Julian Brandt is very, very good.
“I got to know him with the national team and I think he can bring us to a higher level again.
“He can bring us forward on the wings as well as in the centre. It’s a very good transfer for Borussia Dortmund.”
