Dieter Hecking has insisted that Wolfsburg are yet to receive any offers for winger Kevin de Bruyne.
The Belgium international, who joined the German side from Chelsea last summer, has been linked with a move to Manchester City during the current transfer window.
Following his side's 2-1 defeat to Villarreal in the Emirates Cup, the manager told reporters: "There is nothing to say. There is no official offer to Wolfsburg yet. We have no offer from Manchester City. No offer from anybody. Full stop.
"We had a great season and were second last year, Kevin played a big role in this of course and we want to finish the speculation soon.
"As a coach I have to concentrate on my team and we have to make sure we start well on the 14th of August against Frankfurt."
De Bruyne scored 16 goals in 49 appearances for Wolfsburg last season.
