Two soldiers possibly entertained by Liverpool FC stars (3,6)
I believe the answer is:
red giants
'stars' is the definition.
(type of star)
'two soldiers possibly entertained by liverpool fc' is the wordplay.
I cannot really understand how this works, but
'soldiers' could be 'ants' (I've seen this before) and 'ants' is present in the answer.
This explanation may well be incorrect...
(Other definitions for red giants that I've seen before include "Very large stars" , "Stars of high luminosity" .)
