Much more is still required for Marcelo Bielsa to return this famous old club to the Premier League but there is relish that Leeds remembered what they are about on Wednesday night.
These have been troubling weeks, four defeats in seven and the microscope of Skygate, yet Leeds are back atop the Championship with a display that was in Bielsa's image.
The basics were back, a tigerish appetite and a distinctive drive in possession that befuddles so many in this division. Bielsa has bemoaned poor finishing and while Patrick Bamford was guilty of missing chances, it mattered not.
Swansea simply could not deal with the ferocity of the home midfield, Graham Potter's touchline tentativeness matched by his defenders.
Leeds laid claim for a penalty even before Pontus Jansson struck a 20th-minute opener, although it was one the visitors really ought to have stopped.
Bielsa's side had forced a number of corners and this one was only half-cleared, reaching Ezgjan Alioski on the box's edge. He miscued the strike, hitting a hapless defender and bobbling for Jansson to cleverly divert into Erwin Mulder's right-hand corner.
The affable Jansson, who was celebrating his 28th birthday, suggested that Bielsa is not massively friendly with his squad. 'We're not that close, I was closer to Garry Monk and Paul Heckingbottom,' he said. 'It's always football with Marcelo, it's all he lives for.'
That is no bad thing, of course. The same can be said of Pep Guardiola, a Bielsa disciple, and a Manchester City manager who has loaned Leeds a winger who effectively sealed this 11 minutes before half-time.
Alioski was involved again, whipping a wondrous ball in from the left and Jack Harrison – ghosting towards goal unopposed – headed home on the gallop.
Harrison does have detractors but his industry was typical of a Leeds team that appeared desperate to correct a recent imbalance in results.
Swansea offered little as they continue to meander. A Matt Grimes free-kick glanced Kiko Casilla's post. Connor Roberts fired straight at the goalkeeper.
Incredibly they were offered a route back into the game with three minutes left after Luke Ayling hacked down Joel Asoro. Oli McBurnie scored but it was too late.
Poor Daniel James, who saw a deadline day switch to Elland Road collapse, was on the periphery until he was afforded a standing ovation when substituted. 'You're Leeds and you know you are,' sang a packed Elland Road, who want to see him here in the top flight come August.
