That Alvaro 'The Beast' Negredo cost less than misfiring Spurs striker Roberto Soldado seems quite amazing.
Considering Edin Dzeko - who has played the supporting act for the most part - has 15 goals this term is perhaps equally so.
To then assess the fact Manchester City have struck 99 goals so far in what has so far proven a free-scoring season is simply staggering. Lest we forget, it is only January.
If Manuel Pellegrini's side continue to amass goals with such ease and regularity, all sorts of records will be consigned to history.
The sight of Sergio Agüero back during last night's 5-0 win in the FA Cup third round replay over Blackburn will only fuel hopes of fighting on all four fronts to win an unprecedented quadruple.
It can hardly be argued as being beyond the realms of possibility when watching Negredo power his way to a first goal with a bullet header, outmuscling his marker in the process before showing the poise and presence of mind more associated with his attacking contemporaries by lofting the ball home for the second just after the interval.
Dzeko had his say, with two clinical finishes from two Jesus Navas deliveries before Agüero, treated to a hero's welcome when emerging from the team bus before kick-off, and subsequently when warming up and taking to the field, entered stage left and added some gloss to the scoreline, with the Argentinian's strike sandwiched between Dzeko's brace.
Agüero is treated like the messiah at the Etihad and rightly so, but Dzeko and Negredo hardly toiled during his recent absence owing to a calf injury. Indeed, City won eight of the nine games he missed, with the 1-1 draw at Blackburn, which led to last night's televised replay, the only slight on an otherwise irrepressible run of form.
The duo registered six apiece in the time since Agüero hobbled off in the 6-3 demolition of Arsenal and have kept City firmly in the title race, as well as securing a fourth round tie at home to Watford and placing one foot in the Capital One Cup final with a 6-0 thumping of West Ham.
This was the 10th time City have scored four or more goals at the Etihad Stadium and it took City until the second half to really get in the groove. Javi Garcia was sloppy in midfield and, but for Negredo's intervention on the stroke of half-time, there was precious little to get excited about.
As Blackburn tired and City grew in confidence, it was fascinating to watch the 2011/2012 champions dissect their Championship opposition and put them to the sword. We haven't even mentioned reserve frontman Steven Jovetic. On this evidence, the Montenegrin faces a momentous challenge in ousting the three musketeers in Manuel Pellegrini's justifiably-vaunted frontline.
