Fancied a new red mat (6)
I believe the answer is:
dreamt
'fancied' is the definition.
(I've seen this in another clue)
'a new red mat' is the wordplay.
'a new' indicates an anagram.
'red'+'mat'='redmat'
'redmat' is an anagram of 'DREAMT'.
(Other definitions for dreamt that I've seen before include "wasn't practical?" , "Fancied" , "Imagined" , "Had mind pictures while asleep" , "Fantasised" .)
