I think their net spend was minus given they sold Pope, Collins, Cornet, McNeil etc.
It would be a big mentality shift for them to start paying big for players with Kompany at the helm when they refused to do it for Dyche. Kompany has even said he had a four-year strategy for them so promotion this season wasn't essential to their plans (whereas apparently West Brom are in big shit with FFP if they don't go up, which they won't).
