Chelsea are reportedly planning a one-in-one-out transfer policy when the transfer window opens in January, according to the UK Telegraph.
This is in a bid to avoid a repeat of the issues that eventually cost Graham Potter his job.
When Potter was in charge at the start of this year, the Blues made six signings during the winter window.
Only Jorginho, who joined Arsenal, left the first-team squad and it led to a bloated squad, with big-name players regularly omitted from matchday squads.
There were also stories of players having to get dressed in corridors at the training ground because the dressing rooms were too small.
Now, in an effort to avoid the same fate falling on Mauricio Pochettino, Chelsea are planning to tighten up their transfer strategy this time around.
Centre-backs Malang Sarr and Trevoh Chalobah are both reportedly up for sale, as is Ian Maatsen, the left-back who rejected a switch to newly promoted Burnley during the summer.
Armando Broja and Noni Madueke may also seek new challenges elsewhere.
