Agree with
@Fortitude
We shouldn't think only about plugging a space for next season. Instead we should be asking: Long-term, what qualities do we want from our midfielders, and does Fernandes have those kind of qualities? If he's good enough and has the right mentality, we should bring him in.
Some people are looking at our midfield right now and just imagining who would be the best Casemiro replacement. But we could see our midfield shape morph next season, we could see changes in form, injuries, and player development like Fortitude alluded to.
We not only need to add quality in midfield, we need a range of profiles and abilities.
