That's because the script that was written in the conviction that Arsenal's season would grind embarrassingly to a halt there and then at Bramall Lane quite literally got lost in translation thanks ultimately to a Spanish lad who can hardly speak a word of English.
Life has certainly been far from smooth for Manuel Almunia since he joined the Arsenal back in the summer. He has been called all the names under the sun, had his qualities as goalkeeper questioned (albeit with some justification) and through no fault of his own he has found himself in the middle of one of the fiercest controversial debates that the media have whipped up this season.
Yet even though it's unlikely that Almunia has probably ever heard of the saying "Every dog has his day" there is no doubt that Tuesday night proved to be his finest hour in Arsenal colours.
The saves he made both in the penalty shoot out and right at the end of normal time were first class - first class. And, it's only right for someone like me who has had more than a few doubts about his all round abilities as a keeper, to come out on the record and congratulate him for his considerable efforts on the night. He did well and he deserved all the plaudits and headlines he got. That's not to say that the rest of the team didn't do their bit on what was always going to be tricky night - far from it as a matter of fact.
My biggest fear, particularly with so many regulars missing, we would get a repeat of the 1996 replay at Bramall Lane, when we lost 1-0 but, in reality, we really got a chasing.
But whilst it was true that the Blades had two golden chances in the first minute of both the first half and the second half and Harley was denied by Almunia I was proud of the fact that nobody in an Arsenal shirt backed down and bowed to the pressure they were under.
In the last fortnight the Arsenal have been criticised for the absence of British players in their squad but in the midst of a cup-tie that was laced with all the good old fashioned English ingredients you could possibly muster, it was the most blissful of ironies that a combination of a 17 year-old Spaniard and the introduction of an 18 year-old Dutchman at half-time that proved to be the outstanding features for us on the night.
Between them, Cesc Fabregas and Quincy Owusu-Abeyie proved to be dominant forces in driving Arsenal forward both in the second half and in extra time. And if it wasn't for Paddy Kenny and in one instance the crossbar, the two of them would have seen us through long before Almunia even started to perform his heroics.
Predictably, people both in the press and the media not to mention everyone else outside of Highbury branded us as lucky - but, you know what? I don't give a toss.
Yes, it wasn't a stroll for us at Bramall Lane. Yes, we were taken right down to the wire by a Blades side that never wavered in terms of their commitment. And I'm big enough to even agree with Neil Warnock's post match assertion that the game was as tough as any Arsenal have had this season.
But as I alluded to earlier on in this piece, what made me hugely proud was the fact that Arsenal exploded the myth that you don't have to have a large contingent of British pros, seasoned or otherwise, in the ranks to prove that they are capable of showing guts and character, nerve as well as skill. And on Tuesday night's evidence there isn't a man alive that can tell me different.
In fact, show me anyone that has the front to say that any of our foreigners, particularly the kids, were guilty of backing down on the night and I'll show you a liar.
The upshot of Tuesday night's game was that we booked a trip to the Reebok Stadium for a quarter-final tie with Bolton. And although we will go into that game in our usual position as the team with the most prove and the most to lose, the fact is that we will also go into the game knowing full well that we have a score to settle with that lot - big time.
Now, it's time for me to look forward to Saturday's home game against Pompey at Highbury and believe me when I say that this is an intriguing contest.
It would be easy to point to the stats and state the fact that Pompey have only won one of their last seven league games, two of their last twelve in all competitions and say categorically that the brave new world that Milan Mandaric created at Fratton Park in the wake of Harry Redknapp's acrimonious departure and eventual defection down the road to Southampton has not worked out.
You could also say that the sale of Amdy Faye, who was definite favourite, to Newcastle and even arguably the departure of Eyal Berkovic has probably done them more harm than good if only in as much as they were capable influencing proceedings for them.
But last week, Pompey went to Old Trafford and almost made and showed, not for the first time to be fair, that they had the ability to raise their game on the big stage. Forget what the papers said, United knew that they had been in a real game by the time it was all over.
Whatever people think of Pompey, the fact is that there are very few teams that can boast the kind of pace and power up front that they possess - and the unpredictability.
Yakubu may be the main man but particularly with Campbell missing from our ranks, we cannot afford to underestimate the ability of lads like Lua Lua, Kamara and Ricardo Fuller.
Given that quartet and the fact that Patrik Berger is fit and available as well to prompt things for them, nobody can say that they are without a chance particularly if they can keep the match close for long enough.
I will be at Highbury to see this game on Saturday and I would be more than happy if we staged a repeat of the last time I was at Highbury to see us play this lot in the top flight. It was way back in 1987 in the days when I was a regular on the old North Bank terraces and we won 6-0.
I have a feeling that I may be asking for a little bit too much this time around though.
