Footballers given rock? That's a sneaky trick! (4,3)
I believe the answer is:
fast one
'sneaky trick' is the definition.
'fast one' can be an answer for 'trick' (pulling a fast one is playing a trick). I am not sure about the 'sneaky' bit.
'footballers given rock?' is the wordplay.
'footballers' becomes 'FA' (Football Association abbreviation).
'given' says to put letters next to each other.
'rock?' becomes 'stone' ('stone' can be a synonym of 'rock').
'fa'+'stone'='FAST ONE'
'that's a' acts as a link.
Can you help me to learn more?
(Other definitions for fast one that I've seen before include "might be pulled by 20 [HUSTLER] ?" , "Such as Bolt" , "may have been pulled in cheating allegation?" , "Runner" .)
