Eriksen was one of those who I had on my mind when I was writing. There are other players like Kante (if we go for DM) or Koke. Though I am not sure anyone fit.
Point is, we might not need a 23-25 years old midfielder next. Not saying we should go for old one, but this gives us more flexibility.
Koke is too expensive and far from his best form (I won't say he's done at 27 but he's played a lot of games under Simeone's physically exhaustive system) so I wouldn't go after him. Wouldn't mind Kante but it's unlikely. He'll also be 29 next year so I'd rather look for younger players similar to him.

I prefer FDJ as CDM. I want us to get a more attacking CM, Bruno Fernandes? Currently 7 goals and 5 assists in 10 games, that is crazy. However, I am going to be honest and say I have only watched one game.
Eriksen is a good option too while Ruiz is the ideal one. 1- Ruiz 2- Eriksen and 3- Fernandes
I also do rate and like Eduardo Camavinga but that is going to be way too many.
Busquets, Vidal and Rakitic
+ FDJ, Arthur and Alena
+ Puig and O. Busquets
+ Ilaix Moriba and Pedri
There was an article in MD or Sport a few days ago that Abidal likes Camavinga very much. Not very likely because he would cost too much for this but I wouldn't mind signing him and let him go on loan for a season or two.
Raki, Vidal and most likely Alena won't be here anymore next season and I hope Busi won't stay for more than 2 years. I like Roberto's versatility but he also could be a candidate to be sold if we get another starting calibre midfielder and his role will diminish further in a year or two.
I doubt Oriol will ever make it at Barça. Pedri is still unproven on a top level and Ilaix even moreso. They could be part of our first team in 2-3 years but their development could also go wrong at any point so we shouldn't just reserve future first team spots for them and not bring players who can help us immediately. We've made this mistake in the past and waited for some of the youngsters who then never really arrived.
If/When they will be good enough they'll get a chance. You can never have enough good midfielders but I wouldn't mind if we would sometime in the next 4-5 years came into a situation when we could actually sell from a point of strength so we could sell one of the midfielders (who we otherwise wouldn't want/need to sell but we could afford to do that because we would have a younger equally good and possibly better player already prepared to take his spot) while stile at their prime (around 27-28) for big money instead of waiting for them to decline. That would mean to have a great midfield depth but we are still far away from that although our situation is improving.
