One puts the squeeze on Tom's team (10)
I believe the answer is:
thumbscrew
'one puts the squeeze on' is the definition.
(torture device squeezing a thumb)
'tom's team' is the wordplay.
'tom's' becomes 'Thumb's' (folklore character Tom Thumb).
'team' becomes 'crew' (crew is a kind of team).
'thumbs'+'crew'='THUMBSCREW'
(Other definitions for thumbscrew that I've seen before include "excruciating instrument" , "It puts the squeeze on" , "agonised by it?" , "That could be unpleasant!" , "Instrument of torture (crushing the pollex)" .)
