World Cup 2026 - Semifinal Network Visualisation

I have listened to L's editorial guidance and am posting the post with a deadline. Austrian and British Grand Prix scrutineering posts are in the works, as is the first of the weekly Tour de France posts. I am making no promises on timelines because a work project is stealing my time. 

We're down to four teams and the network graph looks like this. Unlabelled network graph of the teams in the quarterfinals.  Smaller circles representing smaller numbers of interactions are red and the colour moves towards creamy white as the circles get larger.  Three of the teams are sort of together in the centre right.  One sticks out slightly to the right. 

The teams are close together, but one sticks out. Labelled network graph of the teams in the quarterfinals.  Smaller circles representing smaller numbers of interactions are red and the colour moves towards creamy white as the circles get larger.  Three of the teams (England, Spain and France) are sort of together in the centre right.  One, Argentina, sticks out slightly to the right. 
Sort of understandably, being as Argentina is on a different continent to the other finalists, they are the team slightly further away from the others. 

The thing I find intriguing is that each national team has one club team close to it, because that club team provides a lot of national team representatives. For Argentina, it is Atlético Madrid (my heart belongs to Diego Simeone), England have Manchester City, France have Paris Saint Germain and Spain have Barcelona. 

It shows the financial strength of European football that the club team with the most players playing for Argentina is Atlético Madrid, not a team closer to home. 

The club teams with the most representatives left are Barcelona with 10, Atlético Madrid with 9 and Arsenal with 8. 

England are just about the team closest to the centre, with Chelsea the club team closest. 

There's something interesting going on in the community view. Although there are only 4 teams left, there are 8 communities. The same diagram as before, but coloured by community.  The eight colours are four large circles, dark grey, lilac, green and light blue.  There are four smaller communities, they are pale brown, orange, pink and darker green. Labelled, it's clear that four of the communities are the nations, and the others are those teams that link more than one country (with some exceptions). The same diagram as before, but coloured by community and labelled.  The eight colours are four large circles, dark grey (Spain), lilac (Argentina), green (England) and light blue (France).  There are four smaller communities, they are pale brown (Inter Milan which links Argentina and France), orange (Chelsea who have at least 1 player in each remaining team), pink (Crystal Palace who link England, France and Spain) and darker green (Bayer Leverkusen who link Argentina, Spain and England). 

The thing that intrigues me is that some teams aren't separate communities even though they link multiple teams. 

I think that happens when most of the players play for one national team, for instance of the five Aston Villa players left, three play for England. 

Chelsea will have a player in the final no matter what combination of teams wins the semifinal matches. 

Making predictions at this point is almost impossible, but the diagram says England and unclear because of how equidistant Spain and France are from the centre.
