Oscar and Frank Lampard scored first-half goals as Chelsea marked the start of Jose Mourinho's second spell as Blues manager with victory over Hull.
Lampard had an early penalty saved by Allan McGregor before Kevin De Bruyne set Oscar up to slot the hosts ahead.
McGregor again thwarted Lampard, but the England midfielder responded with a superb free-kick to double the lead.
Newly-promoted Hull rallied after half-time but could not force their way back as Chelsea comfortably secured the win.
