Is the correct answer.
Why would we say £137m+ only to accept say £80m and then look like complete dickheads? One thing we can say about our club is that it is well run, by professionals who know what they are doing, not a bunch of amateurs. And that would be amateurish in the extreme.
No, the £137m was genuine and it was measured. It doesn't say "Sané is not available for sale at any price", since that would be untrue. If that was the case, we would have said so. It says, "Ok Bayern, if you're that desperate, you can have him for £137m". Of course at the fees being asked, we fully, 100%, expect them to shut up. Which ultimately they will do.
