England boss Fabio Capello has form concerns about Manchester United defender Rio Ferdinand.

The Sunday Mirror says United boss Sir Alex Ferguson may have hit out angrily with claims that people have it in for Ferdinand, but the defender's erratic form is worrying Capello. The Italian has made his feelings known publicly and is threatening to take drastic action unless Ferdinand's form improves.

That could result in the ultimate humiliation for Ferdinand with Capello weighing up whether or not to axe him in favour of West Ham's Matthew Upson for the game against Brazil.
