Frank Lampard is primed for an emotional return to Chelsea to replace Maurizio Sarri after his appointment as Juventus manager was confirmed on Sunday.
The lure of the job is obvious for Lampard but it will not be an easy task.
Here, Sportsmail takes a look at some of the challenges facing Chelsea's manager-in-waiting Lampard.
Frank Lampard is set for an emotional return to Chelsea to replace Maurizio Sarri as manager
The English midfielder won a host of honours with Chelsea - including the Champions League
One of the low points for Maurizio Sarri during his brief Chelsea stay was hearing his own supporters respond to watching his team with chants of 'f*** Sarri-ball.'
The plaudits he received for his football in Napoli were not replicated in England and Sarri decided it was best to return to Italy rather than try and persist.
Lampard will return with untold credit in the bank as a club legend. The fact that his football will be different too would further make his appointment a welcome change.

Jody Morris will come with him from Derby and remain Lampard's right-hand man.

Morris is a former Chelsea midfielder who came through the club's academy before going on to coach in the academy.
Joe Edwards worked alongside Morris and has been earmarked for a promotion from head of the under-23s to a first-team role in Lampard's new setup.
Claude Makalele has been lined up for a role alongside a number of other ex-Chelsea players looking after the clubs army of youth players.
And overseeing the new structure will be Petr Cech who is set to return as sporting director once his Arsenal contract expires at the end of this month.
