Next to British and European team (6)
I believe the answer is:
beside
'next to' is the definition.
(I've seen this before)
'british and european team' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'and' is a charade indicator (letters next to each other).
'european' becomes 'E' (abbreviation e.g. EU).
'team' becomes 'side' (both can mean a sports team).
'b'+'e'+'side'='BESIDE'
(Other definitions for beside that I've seen before include "Next door to" , "Very near to" , "Adjacent to" , "Next to - compared with" , "Neighbours" .)
