Depends really how the rest of the season goes. On current form can't really justify many going to better clubs, the whole team has been frankly atrocious and they have to hold some responsibility. The moment they step out onto that field the responsibility lies with them to perform, nothing the manager says or does has much impact or bearing. To put it simply they haven't performed either the tactics or even the basics of football close to an acceptable standard, and that does not solely go back to Martinez.
