– FA spokesman
It is disappointing that after a great game and advert for the Premier League that we are discussing this issue.
We will work with the clubs and authorities to identify those responsible and support the strongest sanctions available, including life bans.
We condemn any such acts and it is simply unacceptable that any player is exposed to injury in this way. To witness Rio Ferdinand leaving the field with a cut above his eye to receive treatment is appalling.
Nine people have been charged following the Manchester derby on Saturday, police said. In the match Manchester United defender Rio Ferdinand was hit in the head by a coin thrown from the crowd. None of the charges relate to this incident.
