Leeds continued their unbeaten start to the season as they secured a famous win over Chelsea's new-look team with a display which will cause Thomas Tuchel nightmares.
Chelsea, who spent over £170m on players over the summer, were the architects of their own downfall in the first half. Edouard Mendy gifted Leeds the opener by miscontrolling a backpass, allowing Brendan Aaronsen to pounce.
Four minutes later Raheem Sterling gave away a free-kick on the edge of the box, from which Rodrigo scored his fourth of the season after Jack Harrison's delivery.
But Leeds also out-fought their opponents, particularly in midfield, in echoes of the famous historical battles between the two rivals.
