You couldn't miss the irony of Thomas Tuchel's fast, fluid and progressive Chelsea overpowering Antonio Conte's tired, turgid and laboured Spurs.
The most animated Conte got was for the two penalty calls that were rightly overturned by VAR, but other than that his almost puzzled look over the two-legged tie invoked memories of his pretty miserable second season at Stamford Bridge where all the joy of the previous year was sapped out.
Maybe Conte longed for the days he was once the enigmatic figure leading Chelsea into a brave new dawn like Tuchel is now. He was once lauded as the club's next talismanic figure like Jose Mourinho.
But his toxic fallout very much began the four-year spiral that led to Tuchel, who now is showing the way for hopefully something longer-lasting.
Tuchel, for the second week in a row, used a 4-2-2-2 formation. A system we delved into last week that was used by the German in his days at Borussia Dortmund and specifically helped in the first leg to find the best form of Hakim Ziyech.
But this time it was his much-maligned attacking duo of Romelu Lukaku and Timo Werner who benefitted.
Although neither scored, the unpredictability and chaos the formation caused Conte's men in the opening 35 minutes provided a glimpse of the future under Tuchel.
Lukaku, like in the first leg, was able to be used in more varied ways, specifically running from his favoured right-hand channel where he was so devastating for Inter Milan.
Also, the ability to hit long passes over and behind the Spurs defence meant both Lukaku and Werner were able to penetrate space consistently.
In the case of Werner, whose limitations can be felt when asked to construct play on the ball, the number of bodies surrounding him meant the task of creating or beating several opponents was left to others.
Chelsea's intense pressing and quick tempo on the ball facilitated the fluidity of movement that meant the formation altered between a 3-4-3, 4-2-2-2 and a 4-2-3-1 all in the first half as noted by Expected Chelsea.
Tuchel was asked about the recent change in shape post-game and if it's something supporters can expect to see more consistently moving forward.
"If it makes sense and we think it makes sense we can see it again. We have played it now twice and in both games we were very committed to the structure and very disciplined.
"So well done to the team, full credit to them that they are open to some adjustments that give us more options and maybe makes us a bit more unpredictable.
"Of course, today we used it again for the build-up but defended in a back five. It's good to have these options but it needs to fit into what we expect and which spaces we expect to find. We will decide from match to match."
In addition to the exciting formation change, the only goal of Wednesday's game, a header from Antonio Rudiger, once again demonstrated Chelsea's threat from set-pieces.
The European champions have netted four goals from set-pieces against Spurs alone this season.
Albeit one of those could be dismissed as the calamitous Ben Davies own-goal that all but sealed Spurs' fate at Stamford Bridge, though the other three were of Chelsea's making.
Back in the 3-0 win in September, Thiago Silva's header and Rudiger's right-footed strike both came from corners.
A lot of the credit for Chelsea's proficiency from set-pieces goes to coach Anthony Barry who has taken responsibility for them under Frank Lampard and Thomas Tuchel.
Tuchel credited Barry's work back in October after Andreas Christensen scored his first Chelsea goal against Malmo, rounding off a well-worked move from a corner.
Rudiger's latest header takes the tally of goals from corners this season up to 12. One suspects Barry's value will only increase before May.
