Borussia Dortmund chief Michael Zorc accepts Marco Reus' rising star will attract interest from bigger clubs.
Reus has been linked with Manchester United and Barcelona this season.
"When you play football like we do, then it is completely normal that our team attracts such rumours," said Zorc.
"It no longer bothers me. This is even an award. And for Marco Reus I know this much: He is also a key player and also a Dortmunder.
"I would most like him to end his career with us."
