Pay attention after goalie's beginning to shine (7)
I believe the answer is:
glisten
'shine' is the definition.
('glisten' can be a synonym of 'shine')
'pay attention after goalie's beginning' is the wordplay.
'pay attention' becomes 'listen' (I've seen this before).
'after' says to put letters next to each other.
'beginning' suggests taking the first letters.
The initial letter of 'goalies' is 'g'.
'listen' after 'g' is 'GLISTEN'.
'to' is the link.
(Other definitions for glisten that I've seen before include "Glow from reflection" , "Gleam by reflecting light" , "look bright" , "Shine or sparkle wetly" , "Shine with reflected light" .)
