Just getting the feeling Woodward is going for a managerial change + squad overhaul next summer and so hasn't backed Jose, since any new signings might not be to the fancy of the next manager. Plus, trying to override Jose's desire to sell Martial as well seems telling.
Even if Jose leads us to the title (hypothetically!!), I think there will be a handshake and departure via mutual consent next summer. In which case, not making any further signings makes sense, but it comes at the cost of one more dreary season.
