Player from Barça oddly missing height (5)
I believe the answer is:
actor
'player' is the definition.
(synonyms)
'barca oddly missing height' is the wordplay.
'oddly missing' indicates alternate letters (letters in odd-numbered positions removed).
'height' becomes 'tor' (I've seen this in another clue).
The alternating letters of 'barca' are 'ac'.
'ac'+'tor'='ACTOR'
'from' is the link.
(Other definitions for actor that I've seen before include "Person performing on stage or screen" , "Croat (anag.)" , "Theatre player" , "Dramatic artist" , "One in a play" .)
