Behind after a goal, finally shots go in here (5)

Ross

I believe the answer is:

album

I'm a little stuck... Click here to teach me more about this clue!

'shots go in here' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'behind after a goal finally' is the wordplay.
'behind' becomes 'bum' (synonyms).
'after' is a charade indicator (letters next to each other).
'finally' says to take the final letters.
The final letter of 'goal' is 'l'.
'a'+'l'='al'
'bum' put after 'al' is 'ALBUM'.

Can you help me to learn more?

(Other definitions for album that I've seen before include "Book for stamps/photos" , "Book of blank pages for collectables, memorabilia etc." , "Book for filling in" , "CD, say" , "Collection of photographs" .)
