Memorable moments from top-class matches? (10)
I believe the answer is:
highlights
'memorable moments' is the definition.
'top-class matches?' is the wordplay.
'top-class' becomes 'high'.
'matches?' becomes 'lights' (match is a kind of light).
'high'+'lights'='HIGHLIGHTS'
'from' acts as a link.
(Other definitions for highlights that I've seen before include "Points out" , "Most important or exciting parts" , "Outstanding features" .)
