Eminent performer, in teams or otherwise (7)
I believe the answer is:
maestro
'eminent performer' is the definition.
'maestro' can be an answer for 'performer' (I have seen 'Outstanding performer ' mean 'maestro' so perhaps 'performer' could also mean 'maestro'). I am not certain of the 'eminent' bit.
'teams or otherwise' is the wordplay.
'otherwise' indicates an anagram.
'teams'+'or'='teamsor'
'teamsor' is an anagram of 'MAESTRO'.
'in' is the link.
Can you help me to learn more?
(Other definitions for maestro that I've seen before include "special performer" , "Are most in favour of a foreign master?" , "musical genius" , "Distinguished artist" , "best in field" .)
