Spanish hero turning up in Icelandic league (2,3)
I believe the answer is:
el cid
'spanish hero' is the definition.
(I've seen this before)
'turning up in icelandic league' is the wordplay.
'turning up' says the letters should be written in reverse.
'in' indicates a hidden word.
'dicle' is hidden within 'icelandic league'.
'dicle' written backwards gives 'EL CID'.
(Other definitions for el cid that I've seen before include "Eleventh Century Spanish hero" , "11th century Spanish hero" , "Historic fighter" , "Role of Charlton" , "Rodrigo Diaz de Vivar was his original name" .)
