Personally I think the stance the board take in requiring good value for money with signings is very sensible.
In housing terms, if you wanted to buy a £200K house, why would you pay £400K, just because that is what the vendor is asking for, and because they know you have money ?
History has shown that there are plenty of good players out there who don't require massive fees to be paid. VVD from Celtic to Southampton. Mahrez, even Kante to us ...
The onus is on the scouting teams to find them !
I wouldn't be surprised if the club privately love all the media links with "name" expensive players, while they work diligently behind the scenes to secure under the radar targets.
If Mr Rudiger is announced today, then good luck to him. Full 16-cap German international at age 24 can't be too bad ? His vocal stance on racism in Italian football suggests he has some leadership qualities as well.
