Manchester United winger Ashley Young has expressed concern over the security of players after team-mate Rio Ferdinand was struck by an object during the Manchester derby.
It could have taken Rio's eye out and you've seen the cut on his head.
When 'Wazza' [Rooney] was taking a corner there were so many objects being thrown on to the pitch as well and, on another day, if the pitch had not been so wet, the fan who came on to the pitch wouldn't have slipped over and could have attacked Rio.
It's not nice to see that and hopefully it'll be dealt with.
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.
