Chelsea's Defensive Frailties and Fatigue
The Blues' defensive issues were less about tactics and more about execution. In the second half, lethargy and poor pressing coordination led to unorganized out-of-possession movements, leaving the team vulnerable.
Fulham, meanwhile, transitioned to a more aggressive out-of-possession approach, pressing Chelsea's center-backs early and having their second line shift across. As Chelsea's sharpness in possession waned, breaking Fulham’s press became increasingly difficult.
As for Fulham in-possession, they'd form a 3-2-5/3-1-6 with the wingbacks pushing up to provide the width, Traore and Iwobi playing as 10s in the half-space, and Pereira dropping in and out from the midfield and frontline.

Moreover, Chelsea’s middle-third defensive strategy revealed a disjointed mix of man-oriented responsibilities for some players and zonal marking for others. This inconsistency opened spaces for Fulham to exploit. Fatigue also played a psychological role, with Chelsea players often unsure when to press or drop off. Numerous lapses in rest defence left the team exposed, further complicating their ability to control the game.
Meanwhile, Fulham upped their OOP intensity - looking to transition to press the Chelsea CBs early and have their second line shift across (as discussed previously). With Chelsea now not as crisp in-possession, they found it difficult to break Fulham.pic.twitter.com/CBwCbrhvTX

The fatigue also translated to the psychological side, with Chelsea players switching off on when to jump up and when to drop off. There were numerous situations in the second half where Chelsea's rest defence was thereby left vulnerable.pic.twitter.com/CXt1Kc0SIl

Lack of Tactical Flexibility in Substitutions
A notable criticism of Chelsea’s approach was the lack of impactful substitutions. While the bench lacked depth, there was enough quality to make tactical tweaks beyond replacing Jackson with Christopher Nkunku.
Yesterday, the issue was that Chelsea wanted to press intensely but lacked the energy. The team looked really exhausted. In such situations, I think there are two things a manager can do from a personnel and tactical perspective:

Ultimately, Chelsea’s inability to control the match through possession while leading, combined with recurring defensive issues, resulted in their loss. The defeat halts their momentum and highlights the long road ahead for a developing side aiming to mature into title contenders.
