Would think that once Rodri is back DLF will use Pedri higher up the pitch again.
They have a lot of options and tactical flexibility to rotate or adapt to different opponents. Could play either 4-3-3 which fits better what I think is their best midfield on paper (Rodri, Fabian, Pedri) when they're all fit or change to 4-2-3-1 when bringing on likes of Olmo and Fermin. Or if starting Zubi and don't trust him to play a single pivot.
But Rodri, Zubi, Fabian, Merino, Pedri, Olmo, Fermin is probably the best NT midfield both in terms of quality and especially depth since 08-12 Spain.
