However, Marvin Angulo (Costa Rican) is currently at Zaragoza, and I noticed that for him the required amount is absurd 3650 days - 10 years!! Here's a screenshot:

How come it is so? It's madness, he'll never get an EU passport, and thanks to the *** British work permit system, I (Nottingham Forest) won't be able to sign him as he simply won't get a god damn work permit.
