Is it? The entire season consisted of everyone stating over and over that we have no midfield; that every team from top to bottom would overrun and play through our abysmal midfield with ease. Yet now apparently all we need is De Jong to singlehandedly fix the entire midfield issue that has been plaguing us for a decade? Or is Fred/McTominay now good enough? I don't understand the stark contrast in attitude when talking about the midfield
The issue with what we have is a systematic one as well as personnel. Under Ole, and then what Rangnick inherited is a system not capable to build up, recycle possession through the central midfield. We couldn't control the midfield to earn rest period. This leads to the need for workhorses midfielders to compensate for the host of advanced player, attackers who can't maintain any sustainable pressing plan, either under Ole or Rangnick. Yet these workhorses midfielders are not good enough for that task.
With ETH, I guess the vision is to gain more control of the possession. We can't just go buy player to fix the issue of previous regime while disregarding the vision going forward. As LVG tenure showed, we didn't need allstars in every position to win possession game. The more possession you have the less you have to chase. ETH can coach to that certain level, hopefully.
With that system change, we need certain key players to make the system competitive rather than just mere serviceable, and FdJ is that type of player who can contribute greatly both defensively and creatively. You only need to watch Netherland NT and see what their midfield consist to see that as bad as Fred is, it's not the end of the world if you build the team around FdJ. You have VDB who was part of Ajax midfield the last season FdJ was there.
We have ETH now, and FdJ is a great help to fulfill his vision. That's fixing personnel and systematic midfield issue,.
