Chelsea erred — unruly supporters egging others on (12)

Ross

I believe the answer is:

cheerleaders

'supporters egging others on' is the definition.

'chelsea erred unruly' is the wordplay.
'unruly' indicates an anagram.
'chelsea'+'erred'='chelseaerred'
'chelseaerred' with letters rearranged gives 'CHEERLEADERS'.

(Another definition for cheerleaders that I've seen is " Those rousing the crowd in support".)

I've seen this clue in The Times.
