Team’s salvation left up in the air (5,5)
I believe the answer is:
aston villa
'team's' is the definition.
(I've seen this before)
'salvation left up in the air' is the wordplay.
'left' becomes 'L' (common abbreviation).
'up in the air' indicates an anagram.
'salvation'+'l'='salvationl'
'salvationl' is an anagram of 'ASTON VILLA'.
(Other definitions for aston villa that I've seen before include "Vital loans (anag.)" , "Birmingham football club" , "side" , "See team in Midlands" , "Football team" .)
