Leeds were well worth the three points, as Jaka Bijol, Ao Tanaka and Dominic Calvert-Lewin struck for the hosts.
Farke told LUTV: “This is why we have worked so desperately in the past, to bring us back on this level. We want this magic night.
"Unbelievable atmosphere tonight, playing one of the best sides in the world, and to win this game and also deserve to, back to our best defensive behaviour, scored three goals, could have scored perhaps even a few more.
"Of course, it was expected, it was a tough night when you had to suffer a bit, Chelsea had lots of possession, but I think there's also no doubt that we deserve to win this game.
"So we were better in shots and shots on target, the expected goals and chances, big chances, so set pieces, so I think we deserve to win this game and this is a great feeling for us.
“I always spoke about, of course, we have to be as a promoted side a bit more flexible than a side who perhaps dominates a league,” the Boss added on structural changes. “I would love to bring our approach always easily on the pitch and dominate the game with 80% possession, but sometimes also, when you face the best sides, you have to mirror them.
“You have to take their strength away; you have to allow them possession in areas when they can't hurt you and sometimes you have to tweak your formation also a little bit.
“Unbelievable shift from the lads, physical outperformance again of the opponent, second to none. This team is top fit. They showed great heart, great character, great unity, great fighting spirit also.
“It felt also a long time coming because we had also in the last two games really many good results, especially this top half at Man City, but also last home game.”
