Footballers welcome ties being off for a party (6)
I believe the answer is:
fiesta
'a party' is the definition.
(I've seen this before)
'footballers welcome ties being off' is the wordplay.
'footballers' becomes 'fa' (Football Association abbreviation).
'welcome' is an insertion indicator (in sense of 'inviting in').
'being off' indicates an anagram.
'ties' with letters rearranged gives 'iest'.
'fa' going around 'iest' is 'FIESTA'.
'for' acts as a link.
(Other definitions for fiesta that I've seen before include "Outdoor celebration" , "Religious festival in Hispanic communities" , "foreign holiday" , "(Spanish) religious festival" , "Holiday; carnival" .)
