I don't see Florentino doing it
I think he should, but i don't see it happening unless Zidane delivers a big trophy and then threatens to quit if Flo doesn't do everything he can to sign him
Btw, Modric is on his last legs, Ceballos and James don't count and we currently have Casemiro, Valverde, Kroos and Modric as true central midfielders. We're thin. Pogba could easily slot in either Kroos or Valverde's roles without much trouble, and give us a 3 man starting-quality rotation for 2 positions.
As to Odegaard, i'm not sure whether he could fit in midfield next to Kroos. Modric made it work because he was very mobile and an actually very good positional defender in midfield. I see him more as part of the front 3. Besides, he's on loan for two years, not sure we'll be able to bring him back before then
