Well he was converted to a FB and flourished [to an extent] there. Enough to get recruited by Pep and under his usual 50m fullback price range.
Alot of decent attackers with good fundamentals make interesting fullback conversations. Even Jesus Navas found a way to prolong his career there.
I think from LaMasia Fabio Blanco has the closest traits for this, though he did look horrible as a RB In a few early preseason minutes with the first team admittedly.
