Dutch player leaving United, ringing round to cancel (3,3)
I believe the answer is:
cry off
'cancel' is the definition.
(cry off can mean to cancel or withdraw)
'dutch player leaving united ringing round' is the wordplay.
'dutch player' becomes 'Cruyff' (Dutch footballer Johan Cruyff).
'leaving' indicates named letters should be taken away.
'united' becomes 'U' (abbreviation).
'ringing' means one lot of letters goes inside another.
'round' becomes 'o' (round can mean a round object).
'cruyff' with 'u' taken out is 'cryff'.
'cryff' going around 'o' is 'CRY OFF'.
'to' acts as a link.
(Other definitions for cry off that I've seen before include "Pull out" , "Scratch" , "Back out (from an agreement)" , "Fail to keep an arrangement" , "Withdraw from engagement - in tears" .)
