No chance of losing anyone in January.
Wouldn't even worry so much about the players, they sold Maguire for 80 million, bought Soyuncu and went ahead like nothing happened. Their recruitment has been brilliant. Tielemans just signed and I doubt anyone will offer huge sums for him, so Maddison is the only one I see being heavily targeted. Arsenal, United most likely, but can't see other top clubs around the Europe going in as the price will be around 100 million (his contract is until 2023). I mean, if Maguire went for 80, Maddison price will be even crazier. And for that price, they can certainly find replacement.
Pereira have contract until 2023, Ndidi until 2024, so pretty much same story. If you want them, you will have to massively overpay.
Their biggest challenge will be keeping, even replacing Rodgers as he won't be there for long. If I were them, I would look more in that direction.
