With a team completely on top? Indeed so, for a change (3-5)
I believe the answer is:
one-sided
'with a team completely on top?' is the definition.
(as in a one-sided game)
'indeed so for a change' is the wordplay.
'for a change' is an anagram indicator.
'indeed'+'so'='indeedso'
'indeedso' is an anagram of 'ONE-SIDED'.
(Other definitions for one-sided that I've seen before include "So denied being partisan or unfair" , "Biased, favouring one part over another" , "Unequal like contest between badly matched opponents" , "Indeed so (anag.)" , "Unbalanced" .)
