It was remarkable that the first half hadn't produced a goal but the deadlock was broken five minutes after the break as Grant emphatically headed a King cross past O'Neill.
When the desired early goal didn't materialise, Chelsea's play became a bit more frantic, but once Branislav Ivanovic had broken the deadlock in the second half, they began to show glimpses of the verve which won them the League and FA Cup double last season and helped them make such an electric start to this campaign.
