A team's unrelated remarks (6)

I believe the answer is:

asides

'unrelated remarks' is the definition.
(an aside is an incidental remark)

'a team's' is the wordplay.
'team's' becomes 'side's' (both can mean a sports team).
'a'+'sides'='ASIDES'

(Other definitions for asides that I've seen before include "not everyone hears them" , "Incidental remarks" , "Stage-whispers" , "Remarks to an audience" , "Words spoken on stage" .)

I've seen this clue in The Telegraph.
