Thankfully there was only one game that went to penalties. I know they’re probably the least worst method, but that doesn’t mean I have to like them.
Semi-final diagram –
It makes sense that Portugal and Spain are locked together, while Germany and Italy hang off the centre, given the number of Portuguese players that play in Spain, and how most of Germany and Italy’s players play in the league of their home nation. Real Madrid still contribute the most players (10).
If you view the diagram as communities, they are Italy, Spain, Germany, Portugal, Real Madrid and Athletico Madrid. Why the last one I do not know.
