The always-excellent CIES Football Oberservatory recently put together a data-driven World Cup preview, and they presented a number of findings that are likely of interest to Chelsea supporters.

In particular, I was pleasantly surprised to see that Chelsea's players contributed more to the Brazilian national team in 2013 than any other club in the world.

David Luiz, Oscar, Ramires, and Willian combined to play 2,799 minutes for the Seleção during 2013. Barcelona, the next highest-contributing club, has nearly 1000 less minutes played, despite having Neymar, Dani Alves, and Adriano on offer for big Phil.

While the 23-man squad doesn't have to be finalised until May, the four Chelsea players are virtual locks to be selected.

We may have more infographics in the future, so be sure drop a note in the comments section with what you'd like to see.
