Wouldn't be surprised to see Pep go with Rodri and Fern in a starting 11, against Spurs or Liverpool away.
A rarity for Pep, I know but it will be good to have that option, where Liverpool for instance to start with their workmanlike midfield three across the middle.
I think Fern as a number 8, on occasion in the same team as Rodri, would give us even more balance defensively against certain sides, but also unlock the attacking quality Fern has in his locker, particularly when he was at
Shaktar, where he was brilliant as an attacking midfielder.
