Kiko's surname is Argüello.
'Agnello' means lamb (in Italian, at least). 
Kiko is certainly no lamb.
I think he and Carmen left Spain very early (were they still in their 20s?), presumably having decided that Italy and Rome was where the real power and influence lay.
I see the neo-Cats as a mainly Italian phenomenon, albeit with offshoots now all over the world. Are they strong in Spain, do you know?
