Cech - Blues defence is key

Peter Cech is hopeful Chelsea's defence can help them retain their Premier League title this season.

The Blues' cushion at the top of the standings was cut back down to five points at the weekend as Arsenal triumphed 3-0 over 10-man Manchester City and rivals Manchester United also won at Stoke.

Chelsea laboured to a 2-0 victory over struggling Wolves at Stamford Bridge in a display manager Carlo Ancelotti feels was hindered by their midweek UEFA Champions League trip to Moscow.
