Everything happens for a reason. Yin and yang. Universal balance.
Airy concepts like fate and destiny is probably not much consolation to the likes of Falcao, who have missed this World Cup through injury, but when you look at the effect it has had on Colombia, it could be that the initial bad fortune has become a blessing in disguise for a team looking at the bigger picture.
For the Cafeteros it has thrust James Rodriguez into centre-stage, both positionally and figuratively, and the young playmaker is arguably the tournament's star so far.
For Argentina today, it could be that Sergio Aguero's injury comes as a similar stroke of luck. Of course, any side would hurt from losing a player of Kun's quality when he is playing at 100% but the sad truth is that the Manchester City man has been way short of his best during the World Cup so far.
Troubled by a thigh issue, he has lacked the spark of acceleration that helps him explode past players into dangerous positions, yet Alejandro Sabella, both through loyalty and the insistence of Lionel Messi, has kept Aguero in the side.
Now he is ruled out, it gives “el Pachorra” the chance to balance up a team that hasn't looked at its swashbuckling best yet in Brazil. The lop-sided 4-4-2/4-3-3 was undoubtedly a success in qualifying but that relied on Aguero's movement and speed to make it work. With him far from his peak, the front three that on paper was the best in the tournament lacked the penetration of their qualifying displays, with Aguero now occupying Gonzalo Higuain's space and stifling the both of them.
Fortunately, Lionel Messi has been on hand to bail them out, but it will be a welcome opportunity today for Sabella to shuffle his pack and change things up.
The obvious, direct replacement is to bring in Ezequiel Lavezzi and retain the same shape. 'El Pocho' has been restored to the side after a poor showing at the 2011 Copa America on home soil, and despite his often frustrating final ball – as shown against Nigeria – he has the Aguero-like burst of speed that can see him dash past opponents and pull defences out of shape.
The naturally conservative Sabella may alternatively opt for a midfielder to balance his side out. Maxi Rodriguez was tried in open training but Ricky Alvarez remains an option, and just as Argentina replicated the 3-5-2 used to beat Bosnia in a friendly when they played them at the World Cup, a switch back to a flat 4-4-2 would be reverting to the same shape that beat Switzerland when these two sides last met.
That game was early in Alejandro Sabella's reign and before he (and Messi) had decided that the Barcelona man needed more options around him, but it puts the pressure now on the Argentina coach to make the biggest call of his reign so far. His instinct will tell him to solidify a team that has looked defensively susceptible, but his star player and skipper will tell him to stick with his own preferred shape.
Arguably both would be more effective than carrying a man who wasn't fully fit.
Although Messi doesn't need anyone's injury to propel him to super-stardom as we've seen with Rodriguez and Colombia, if today's reshuffle helps the likes of Higuain or Lavezzi step up to the plate then it truly will be a blessing in disguise, and a possible turning point on the path to World Cup glory.
