Chelsea's key man N'Golo Kante has a new midfield partner this season.
He won the title alongside Nemanja Matic in the 2016/17 campaign but the Serbian hardman was allowed to join rivals Manchester United in a £35m deal.
Young Monaco midfielder Tiemoue Bakayoko was signed for £40m as his replacement and has settled in effortlessly after returning from injury.
The 23-year-old Frenchman made his debut in the 2-1 win away at Spurs in August despite not being fully fit.
Chelsea's Italian boss Antonio Conte still believes there is plenty of room for improvement.
"I think Baka is a good player – he’s 23 years old, don’t forget this," said Conte earlier in September.
"He has a lot of room to improve in the tactical aspect. Also in the physical aspect. He’s working very well and he needs a bit more time than other players to understand our style of football very well.
"I’m very happy because he’s improving a lot. In the last 10 days he improved a lot in the tactical aspect and physical aspect.
"He’s a powerful player, for sure a good signing for us. To have a powerful player in your team is very important, above all in this league. This league is very tough physically. If you are not prepared for this impact you can suffer a lot.
"For sure I’d like to play with him. Now it’s impossible. Not now. I think he’s very close to being totally involved in our idea of football. He can improve a lot with the ball. We are working about this aspect."
Kante and Bakayoko's new song
Travelling Chelsea fans were filmed in Atletico's new Wanda Metropolitano showcasing their new Bakayoko song ft. Kante.
The video, circulated by Bleacher Report, has over 3000 retweets and is sure to be heard at Stamford Bridge when the Blues host table-topping Manchester City on Saturday evening.
Spanish midfielder Cesc Fabregas has also been excellent so far this season and the wealth of options in Chelsea's midfield is stronger than ever.
England international Danny Drinkwater was signed for £35m from Leicester City but is yet to make his debut for the Blues.
