But he told BILD: "The bosses see something in Leroy, they see something in me. That's why they bought me. That's why they might buy him. I want to develop here.
"If Leroy should come to us, I can learn a lot from him. He is a top winger for his club and for his country.
"The young players are good here. KC - that's Kingsley Coman - and Serge (Gnabry), we're young, hungry to play and I'm sure everyone will get a chance to flourish and shine in this club."
