Match tactics having quietly ignored SE Asian players (7)
I believe the answer is:
gamelan
'asian players' is the definition.
(I've seen this before)
'match tactics having quietly ignored se' is the wordplay.
I cannot really understand how this works, but
'match' could be 'game' (I've seen this before) and 'game' is present in the answer.
The remaining letters 'lan' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gamelan that I've seen before include "Indonesian orchestra" , "exotic orchestra" , "instrument" , "Asian players" , "Asian ensemble" .)
