Derby owner Mel Morris admits Frank Lampard is very close to becoming Chelsea manager.
Lampard is expected to take over the reins at Chelsea following Maurizio Sarri's departure from Stamford Bridge - having shone during his first season in management at Derby.
And Morris has reluctantly accepted that Lampard's return to west London is just a 'matter of time' now, before claiming his appointment has been delayed largely due to the former midfielder being on holiday.
Morris told talkSPORT: 'Frank and I discussed this eventuality. Frank and Chelsea need to have the time now to finalise the transaction between them.
'In fairness, Frank was away on vacation and didn't come back until Friday - that was a big factor.'
When asked about Derby making moves to appoint a new manager, Morris replied: 'We're very keen to get something sorted out in time for the trip to America.'
