Bloomers made by singer joining football team (9)
I believe the answer is:
larkspurs
'bloomers' is the definition.
(type of flowering plant)
'singer joining football team' is the wordplay.
I cannot quite see how this works, but
'singer' could be 'lark' (lark is a kind of birdanimal) and 'lark' is present in the answer.
'team' could be 'spurs' (nickname of Tottenham Hotspur FC) and 'spurs' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'made by' is the link.
Can you help me to learn more?
(Other definitions for larkspurs that I've seen before include "Common names for delphiniums" , "bloomers" .)
