Chelsea are a solid PL TOP4 team that should be finishing around 80 points or more and should make good runs in CL, they have a good mix of experience in Kante, Giroud, Azpilicueta, Jorginho, Ziyech and abundance of young talent in Havertz, Werner, Mount, Pulisic, Chilwell, Abraham, Hudson-Odoi etc. Of course we could've beaten them with a real coach, but they're not bang average either, if they continue building under Tuchel, I expect them to regularly feature in CL knockouts the next few years.
Transfermarkt values by any means aren't scientifically proven to represent the real transfer fees (although for large transfers of popular players they seem to be pretty accurate
