Frank Lampard will be assured that he will be given time to try to create a successful new chapter of his Chelsea career as head coach.

Derby County on Tuesday confirmed that Lampard had been given permission to complete a romantic return to Stamford Bridge after granting Chelsea permission to speak to their former midfielder.

It is expected Lampard will be offered a three-year contract worth around £4 million a year to succeed Maurizio Sarri, with the possibility of earning a pay rise if his first ­season is considered a success.

While there will be no guarantee that Lampard will be allowed to see out his contract, there is a hope that, barring the worst-case scenario of a relegation battle, he will be given at least a full season before facing any sort of assessment.

Lampard is one of Chelsea’s most decorated players and their all-time leading scorer, but faces a tough task to recreate immediately that success as head coach, with the club operating under a transfer ban.

There is huge upheaval throughout the club, with a number of staff and backroom changes, which include the return of Petr Cech as technical and performance adviser.

Lampard is set to become the 12th manager of owner Roman Abramovich’s reign and the first Englishman to take charge of the club since Glenn Hoddle in 1993.
