Champion: name for tall winger (5)
I believe the answer is:
heron
'tall winger' is the definition.
(tall bird, something with wings)
'champion name' is the wordplay.
'champion' becomes 'hero' (synonyms).
'name' becomes 'n' (common abbreviation e.g. on forms).
'hero'+'n'='HERON'
'for' acts as a link.
(Other definitions for heron that I've seen before include "flier" , "eg Egret" , "Big bird" , "Bird of the Rhone, strangely" , "Wader" .)
