Position at match containing leaders of team under duress (8)
I believe the answer is:
attitude
'position' is the definition.
('attitude' can be a synonym of 'position')
'at match containing leaders of team under duress' is the wordplay.
'match' becomes 'tie' (I've seen this before**).
'containing' indicates putting letters inside.
'leaders of' says to take the initial letters.
The first letters of 'team under duress' is 'tud'.
'tie' going around 'tud' is 'titude'.
'at'+'titude'='ATTITUDE'
(Other definitions for attitude that I've seen before include "Way of thinking or feeling about something" , "Pose; point of view" , "Opinion or position on something" , "One's position or stance" , "Taut diet may reflect opinion or stance" .)
