And, with Sarri out of the picture, the west London club are expected to name Lampard as their new boss.
In his sole season at the club the 60-year-old Italian - who succeeded Antonio Conte last summer - guided the team to Europa League success, third place in the Premier League and the Carabao Cup final.
Zola previously managed Italian side Cagliari in 2014/15, though he was sacked less than three months after his appointment with the club in the relegation zone. Marcotti explains why he is not sure Sarri is the right fit for Juve before the panel turn their attention to Chelsea's now-vacant managerial position.
Lampard led Derby to the Championship play-off final last season.
"We have made it very clear to everyone, but most importantly to Frank, that we want to retain Frank for the long term", said Morris in a statement reported by BBC Sport.

Claude Makelele will be given a prominent coaching post with the loan group at Chelsea as part of Petr Cech's return to Stamford Bridge to take on a role similar to that of a technical director.
Sarri's departure to Juventus was confirmed on Sunday after just one year at the club.
"I think it would be a major surprise if he doesn't get the job".
Despite his potential concerns, Sinclair believes Lampard will leap at the chance to return to his former club.
Lampard is understood to have been offered a contract extension by his current employers, while Chelsea could have to fork out as much as £4 million in compensation for a deal to go ahead.
