European footballer's caught plague (5)
I believe the answer is:
beset
'plague' is the definition.
(I know that plague can be written as beset)
I don't understand how the remainder of the clue works.
(Other definitions for beset that I've seen before include "Encircled, attacked" , "Hem in, surround" , "Beleaguer" , "Assail or attack on all sides" , "Hemmed in or surrounded" .)
