The implications of this tackle could have been be huge: If Salah was unable to play for his country (it turns out that he has done the almost impossible and is fit), this could have affected Egypt’s chances in the World Cup, and while Egypt is unlikely to be troubling the later rounds of the competition, like a butterfly flapping its wings on the other side of the world, Egypt’s performance could in turn impact how the other teams in its group do - and ultimately affect which country gets to lift the trophy.
This said, Salah’s potential fall is only one of literally millions of data points. One of millions of factors that could ultimately affect the outcome of the competition.
How can we get a handle on what to expect, then? Is there any way to predict how teams will perform? Could Big Data, which has already transformed countless other industries, also unlock a deeper understanding of the beautiful game? Could it predict who will win the World Cup?
