Manchester United's victory at Arsenal came at a major cost.

Defender Phil Jones could be out for a month after being carried off with ankle ligament damage while Nani, Wayne Rooney, Patrice Evra and Michael Carrick all picked up knocks.

Boss Fergie said: "It's not good news. Jones will be out for a while and Carrick was feeling his hamstring in the second half. He just had to sit in the middle of the pitch."

United were already without crocked Rio Ferdinand, Anderson, Tom Cleverley, Ashley Young, Michael Owen, Darren Fletcher and Nemanja Vidic.
