Nah, you're misreading it.
"There are no offers [for Draxler] from not a single club"
Let O be the set of Draxlers for whom offers have been received.
Let β(o) be the number of offers received for an element o β O.
Heldt's statement can be rendered in second order predicate calculus as:
β o β O, β(o) != 1
or equivalently, β o β O, β(o) = 1
From which we can deduce that if an offer has been received for any Draxler at any time, exactly one offer has been received. So the good news is, if we're still in the running for a Draxler, we have no competition!
