Borussia Dortmund chief Michael Zorc remains confident of keeping Marco Reus.
The Germany international is being linked with Manchester United, Barcelona and Manchester City and has been coy about committing to new terms offered by BVB.
But Zorc remains calm about the situation.
"This isn't something we're concerned about and it's obvious Marco isn't either. You can see his response to the rumours on the field. He knows he is important to us and we know we're important to him."
