Best team gets cut (7)
I believe the answer is:
topside
'cut' is the definition.
(I've seen this before)
'best team' is the wordplay.
'best' becomes 'top' (top can mean the very best).
'team' becomes 'side' (both can mean a sports team).
'top'+'side'='TOPSIDE'
'gets' is the link.
(Other definitions for topside that I've seen before include "Dish" , "Outer cut of beef" , "Lean cut of beef, no bone" , "Towards ship's upper decks; part of cut of beef" , "Joint" .)
