Uri perhaps seen with a footballer (7)
I believe the answer is:
cantona
'footballer' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'uri perhaps seen with a' is the wordplay.
'uri perhaps' becomes 'canton' (I can't explain this - if you can you should believe this answer much more).
'seen with' means one lot of letters go next to another.
'canton'+'a'='CANTONA'
Can you help me to learn more?
(Another definition for cantona that I've seen is " Eric -------, Manchester United idol of the 1990s".)
