Tammy Abraham secured a 2-1 victory for Chelsea over fierce rivals, Arsenal in the Premier league on Saturday.
The forward scored a deftly executed finish in the 87th minute to send the blue part of London into a frenzy after midfielder, Jorginho had levelled things earlier.
Arsenal started the game strongly in front of their home support, looking to secure their first win under new manager, Mikel Arteta, and took the lead early on from a Peirre-Emerick Aubameyang header.
Chelsea looked sluggish from then on until manager, Frank Lampard, changed the system, bringing on Jorginho for Emerson and switching to a back four to aid the attack.
There were calls for a red card for Jorginho in the closing stages of the match after he had fouled Arsenal player, Matteo Guendouzi, but the referee opted to wave the calls away, brandishing a yellow to the protesting Lacazatte instead.
Jorginho would go on to score after that incident, setting the wheels in motion for a Chelsea resurgence.
The win leaves Chelsea solidly in 4th position, condemning Arsenal to 12th place and a potential relegation battle.
