His loan at Girona turned him into a man, so to speak.
Pep, Koeman, and Xavi clearly rated him in some way, but he struggled a lot on the physical aspect and got done in easily in 1v1 duels. It seemed like at Girona he started to put the pieces together, and Flick turned him into a versatile, confident machine.
Is he World Class? nah, but he's significantly a much better player now. Even with our suicidal High line, the guy looks comfortable out there in defending and playing out the back.
