Chelsea won't relax - Mourinho

London - Jose Mourinho insists there is no chance of complacency at Stamford Bridge after Chelsea opened up a six-point lead at the top of the English Premiership table.

Mourinho's side extended their advantage over second-placed Manchester City after a 1-1 home draw with Southampton on Sunday and have still played a game less than the chasing pack.

With just nine games remaining, the English title appears destined for the Bridge unless Chelsea make a dramatic collapse.
