Regularly targeted by FA, Roberto Mancini originally managed Forest (4,4)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

T{a}R{g}E{t}E{d} [regularly], FA, R{oberto} + M{ancini} [originally].  ‘Managed’ in the definition is adjectival.  The surface relies on references to football, a subject on which I know very little, but for those in a similar position: FA = Football Association, Roberto Mancini is an Italian former player turned manager, and Forest = Nottingham Forest Football Club. Mancini never managed Forest but did run Manchester City FC for a while.
