Vidic: United will prove staying power

Nemanja Vidic is convinced Manchester United will show their true Premier League title credentials in the second half of the season.

Despite recording their biggest win of the season against Stoke on Saturday, United remain eight points adrift of pace-setters Chelsea and Liverpool - knowing they will probably slip even further behind before Christmas because their scheduled clash with Wigan on December 21 has been postponed due to the World Club Cup.
