The Blues will take on the current La Liga leaders away from home and we need to be at our best to get a positive result.
Yesterday, we asked you to select the best starting XI for our Champions League Round of 16 first leg tie against Atletico Madrid.
The most-liked comment on the post was from our user Michael Fox, who wrote: "I prefer 2nd option, it has more in attack and defence."
Chelsea XI: Mendy, Azpilicueta, Rudiger, Christensen, Alonso, Kante, Mount, Hudson-Odoi, Pulisic, Havertz, Werner
A strong team on paper that has what it takes to beat the strong Atletico side - let's get the win!
