LONDON -- The head of English football is concerned about the recurrence of racism and crowd trouble after Sunday's Manchester derby was marred by United defender Rio Ferdinand being hit by a coin and a fan arrested for racist abuse.

Football Association chairman David Bernstein says "it is deplorable to see those incidents and to see Rio Ferdinand with blood on his face is absolutely terrible."

Coins had been aimed at the United players previously during the game at City, and one hit Ferdinand after Robin van Persie's stoppage-time goal clinched a 3-2 win for United.

A City fan also ran onto the pitch toward Ferdinand but was stopped by City goalkeeper Joe Hart, while a fan was arrested for alleged racial abuse and charged Monday.

Bernstein told Sky Sports television "it's disturbing that we're seeing a recurrence of these types of incidents."
