Sheffield United staged a spirited second-half fightback to pick up a deserved 2-2 draw with Chelsea at Stamford Bridge.
After falling behind to a Tammy Abraham first-half double in the 19th and 43rd minutes, the Blades responded with great confidence and character after the break.
Callum Robinson swept home 46th just after the break before his cross was deflected into the net by Chelsea defender Kurt Zouma in 89th to send the away end wild.
The result means Frank Lampard is still waiting for his first home win as Chelsea manager.
Chelsea face a trip to Wolves after the international break while Sheffield United host Southampton.
