It first became acknowledged wisdom that a club thirsty for glory on all fronts needed four high-class strikers when Manchester United swept the board in 1999.
Dwight Yorke, Andy Cole, Teddy Sheringham and Ole Gunnar Solskjaer all contributed vital goals to the conquest of the treble, tattooing the necessity of such a quartet on English football consciousness in the process.
So why have Manchester City, in allowing Alvaro Negredo to sign for Valencia on loan, decided to flaunt Sir Alex Ferguson’s law?
Admittedly the extent to which any side fields two strikers is far less than it was at the turn of the century, but it’s possible that the Citizens have done themselves a mischief regardless.
A trio of exciting potential line-leaders remain, with Sergio Aguero, Stevan Jovetic and Edin Dzeko 11/2, 16/1 and 25/1 for Premier League top-goalscorer honours respectively.
There’s no denying they’re a triumvirate of the highest calibre, yet between them ‘Kun’ (31) and his Montenegrin associate (28) have missed a massive 59 games over the last two campaigns as per transfermarkt.com.
That’s 13 separate injury spells since August 2012.
How can such a bone-china vanguard be expected to survive the arduous pursuit of trophies on at least three fronts?
While Aguero and Jovetic spent prolonged periods in with the nurse last term, the departed Negredo was contributing 26 strikes in 49 appearances for the Citizens.
Of course the ever-reliable Edin Dzeko abides but, while his qualities are manifold, he is not as liable to provide moments of game-changing inspiration as his starting-berth rivals.
Despite averaging 0.72 goals for every 90 minutes in the Premier League last term his strikes changed the destination of the points on just two occasions.
Meanwhile, Yaya Toure can by no means be relied upon to follow up a scoring season that more than doubled his previous high watermark last term.
As a result City will continue to rely upon two of their most fragile players for the moments of inspiration that win titles.
