Lampard emerged as the stand-out candidate to take over at Stamford Bridge, having made a promising start to his managerial career with Championship side Derby County.
The 40-year-old faces a testing first season in charge as Chelsea face up to the prospect of a two-window transfer ban, though they have appealed the decision.
If the appeal is unsuccessful, Lampard will not be able to make any new signings until next summer and will need to utilise the academy to a far great extent than previous managers of the London giants.
HE’S HOME! 🙌
Frank Lampard is the new Chelsea head coach!
