I find interesting that you and a lot of people thinks like this

I think the exact opposite, its the worst part of the team because all three players you mention do the exact same job,
the 3 stay far too deep and doesn't fight for the ball, are all physically and aerial weak, does have good passing though, but then again doesn't offer that much offensively.
Could be the reason the side backs are playing very offensive and having good games but I prefer to get rid of one of this 3 (read Fabricio there)
and get someone who does want the ball back everytime and cannot be physically dominated like lots of teams did (read Estudiantes there).
Cruzeiro best midfield in last couple of years had Charles doing the dirt job and Ramires who offer something offensively,
you could add one of the 3 actual DMs we have now and that would be a perfect balanced midifield, 3 that are average at both jobs is useless.
Adilson shows glimpses that he knows about that problem, signing Fabinho (at least with good intentions, but he way passed his peak)
and trying to sign Leandro Guerreiro (not that strong but a guarantee that you will win the ball back) but its been 2 years and he still haven't fixed it, so I wonder if he knows at all.
But thats just how I like a midfield, a lot of people disagree with me on this but I stick to my opinion.
We won't win anything big like Libertadores with weak DMs.
