I deliberately left the last update as late as I could so that no changes would fall through the cracks. So, of course, after I post it, I find out that Italy have had to replace Andrea Masi with Michele Visentin.
The diagram now looks like this
Samoa are still the national team closest to the centre, but the club team closest to the centre is now either Agen or Aurillac. It’s probably Aurillac but it’s very close.
Italy have now had to replace three of their players, making them the second most affected team at the World Cup.
