Chelsea are set to announce Frank Lampard as their next manager this week.
The Blues are taking their time as they iron out the finer points of his contract.
But Lampard is set to leave Derby and take up the post at his former club.
Sky Sports says an announcement could be made as early as Thursday.
The 41-year-old is holding final talks about the club's position regarding transfers and their upcoming FIFA transfer embargo.
Lampard wants to understand how much money will be available after their transfer ban is lifted next summer.
