Madrid, Barca and Munich weren't after Rodri at 23 either. We were pretty much unopposed when we signed him.
Phenomenal scouting from Txiki and the board, really. He'd done well at Villarreal and Atletico but not tearing up trees.
Perhaps we were lucky that the position wasn't as fashionable yet as it has become in recent years. The '6' is now arguably the most important position in football (IMO anyway).
