Chelsea evoked the spirit of their Carling Cup victory over Arsenal in 2007 to book their place in this year's FA Cup final.
The Blues won 2-1 that day at the Millennium Stadium after falling behind early on to a goal by Theo Walcott and Didier Drogba was the man who made the difference.
The comparisons extend to the fact the Gunners had a lot of the play that day, but Chelsea had the edge when it came to taking advantage of their openings.
The Blues were often menaced again by the raw pace of Walcott, who gave the north Londoners an 18th minute lead, but they had a defensive robustness which carried the day.
In stark contrast to Arsenal's typical close-passing, the Blues were not afraid to launch the ball from deep, but this is not as inexact a science as it seems when Frank Lampard is the man doing the launching.
The midfielder picked out Florent Malouda for the equaliser with a beautifully weighted ball from the halfway line on 32 minutes and repeated the trick with six minutes remaining to carry Guus Hiddink's men home.
This time it was Drogba, so often a thorn in the Gunners' side, who sprinted clear before rounding Lukasz Fabianski to tap in from the edge of the area.
The logic of the outcome will have been appreciated by Petr Cech, whose nightmare week showed no signs of getting any better when Walcott beat him for the game's opening goal.
The normally ultra-reliable keeper, who showed signs of fragility in conceding seven goals in two games before today's cup tie, looked sluggish in getting down low to Walcott's left foot volley, although in mitigation, Ashley Cole did deflect the Arsenal wiinger's shot with his right hand.
Arsenal carved out the opening when Emmanuel Adebayor played a simple ball to the byline for Kieran Gibbs to oull back invitingly.
But in the 33rd minute, Florent Malouda levelled it up, The midfielder, who has been a revelation in recent weeks, latched on to the Lampard pass and cut inside Emmanuel Eboue before drilling home inside Fabianski's near post.
Anelka then fizzed a low left footer onto a post from outside the area - the shot having the beating of Fabianski - but it was not until the second half that Chelsea administered their coup de grace.
Theirs was a study in organisation and patience during the second half because they seldom ventured forward in great numbers. But they took comfort from a far better defensive showing than against Bolton and Liverppool in the previous two games.
Hiddink sprang a surprise in asking Ricardo Carvalho rather than Alex to make way for the returning John Terry at the heart of the defence, but that pairing had a great afternoon and managed to shore up the danger areas.
So it's back to Wembley in six weeks for a likely repeat of the 2007 FA Cup final and, who knows a repeat of the win that day, which was also built on pragmatic, no-nonsence defending. After the Liverpool chaos, that will suit Hiddink and his team just fine.
