Thing that makes France's win disappointing on a footballing level is that the lessons learned aren't so great. France 2018 is a team of great athletes who can perform in the sport of football, it does not have many footballers. They won with set pieces, strength, discipline, speed and gamesmanship.
Even with Mbappe it seems most of the hype comes from the sheer athleticism. The country that produced Platini doesn't have any artists playing football left. Of all French teams I've seen in my lifetime, this is probably the one with the least flair. It's an interesting role reversal, in the 80s through the mid 90s Germany were known for their lack of flair and reliance on strength and discipline while France's 80s side was seen as rich in flair and artistry. Now, Germany hit a low point this tournament while trying to play an audacious form of possession football (that relied on one/two guy covers while 8-9 guys are attacking) and France won it with those qualities they spurned back in the day.
Now this tournament has seen some excellent footballers, KdB, Hazard, Modric, Rakitic and of course Messi..they all lost to France. Even though this France team does not have a footballer of that quality. Of course, most countries do not have access to these types of athletes, but I hope that even ones which may - like Germany - do not go down that route.
