Squad satisfied about touring area (4)
I believe the answer is:
team
'squad' is the definition.
(synonyms)
'satisfied about touring area' is the wordplay.
'satisfied' becomes 'met' (as in 'met the conditions of his contract').
'about' is a reversal indicator.
'touring' means one lot of letters goes inside another (tour can mean to go around).
'area' becomes 'a' (maths abbreviation).
'met' back-to-front is 'tem'.
'tem' enclosing 'a' is 'TEAM'.
(Other definitions for team that I've seen before include "One side in a game" , "People working together" , "A cooperative unit" , "Mate for a group of players" , "Players united" .)
