Sitting fourth, Antonio Conte's team are taking some time to adjust to the amount of competitions they will compete in this season, but the Blues look strong across the board.
Apart from missing cover in one or two positions, the squad is well stacked and it would be a surprise to see too many additions this January when the transfer window reopens.
They have been successful in trusting their French scouts over the past few years, from Eden Hazard to Michy Batshuayi and Tiemoué Bakayoko and there are a couple of players across the channel who should be interesting the Italian this winter.
Here are three Ligue 1 stars who Chelsea should consider signing come the new transfer window.
Lucas Lima – Nantes
A late bloomer, the 26-year-old impressed under Sergio Conceicao last term and is now continuing that under Claudio Ranieri.
France is the breeding ground for that perfect combination of power, pace and crossing ability that makes them able to play in a back four or as a wing-back.
Signing Davide Zappacosta solved Chelsea's cover issues on the right, but reinforcements could still be very useful on the left.
This season, the Brazilian is winning 78 per cent of the 3.2 tackles he attempts per 90 minutes and makes 1.6 interceptions and 1.4 clearances.
What makes him stand out is the number of crosses he is attempting this term. He leads Nantes with 9.3 per 90, an astonishing 3.7 have been accurate. No one in Ligue 1 who has played 200 minutes is achieving more. Only because they have very limited quality up front has the Brazilian not picked up any assists this season.
Maxime Lopez – Marseille
One position where Chelsea are not struggling this season is in the centre of midfield. They may have sold Nemanja Matic to Manchester United, but with Tiemoué Bakayoko and Danny Drinkwater arriving, Antonio Conte is spoiled for choice.
Linked as a Liverpool transfer target in the past, his minutes have been limited this season so far, making just three starts.
He is still just 19 years old, but if he’s not going to play, he could be tempted with a move abroad.
Great in possession, Lopez can play as a deep-lying playmaker, but then push forward as a box-to-box midfielder and thread devastating passes through defences.
Certainly one for the future, you would normally suggest he stays in France to gain experience, but playing a reduced role at OM could offer Chelsea the chance to pounce.
Ángel Di María – Paris Saint-Germain
The signing of Neymar and Kylian Mbappé put everyone on notice. Places in the PSG attack are difficult to come by and the likes of Ángel Di María, Julian Draxler, Lucas Moura and Javier Pastore are feeding for scraps.
After a bright start to his career at Manchester United, Di María flopped in the Premier League, but that doesn’t mean he won’t be interested in giving it another try.
Life in London would be different and there are enough Spanish speakers to help him settle.
Able to play on either flank, he even excelled with Real Madrid playing in the midfield. Blessed with a stunning left-foot, he’s a different type of winger from Pedro and Willian and could offer an interesting alternative for Conte.
For PSG he has contributed to 70 goals in 96 games, a phenomenal return and one worth of making a move this winter if the situation in Paris doesn’t change.
