Chelsea returned to form after two defeats in a row to beat West Ham 3-0 at Stamford Bridge on Monday night.
The Blues were busy in the summer window, spending more than £200million as Lampard looked to build a side capable of winning the title.
But January could still see ins and out as he continues to put his stamp on the squad.
There have been winners and losers in the Chelsea team as they begin to get a settled starting XI.
With that in mind we take a look at the latest transfer rumours from west London with the January transfer window just round the corner.
Antonio Rudiger exit update
Out of favour centre-back Antonio Rudiger is once again being linked with a move to PSG after manager Thomas Tuchel reportedly advocated his signing recently.
The French giants are currently without Marquinhos and Presnel Kimpembe due to injury, and Rudiger is seen as a good choice due to his experience in Europe and regular top flight football.
90min claims that Chelsea rejected loan bids from PSG for Rudiger in the summer, so they will likely have to settle on a permanent deal.
Seven stars put up for sale
Sky Sports report that as many as seven players are set to be axed in January as Lampard looks to trim his bloated squad.
One of those is said to be Rudiger, along with Andres Christensen, Jorginho, Marcos Alonso, Ross Barkley, Danny Drinkwater and Victor Moses.
It remains to be seen if there will be any takers for those out of favour stars, and at what cost, though.
Two mega signings eyed
The reason those seven players have been put up for sale is to fund mega moves for West Ham midfielder Declan Rice and Borussia Dortmund striker Erling Haaland.
Both men are likely to come at a premium due to their form in recent months.
It seems unlikely that Chelsea will manage to sign both, but even picking up one of Rice or Haaland would be a massive coup.
