I guess I can choose 3
(1)
Brazil 2002 is definitely the best one. It is hands down the best team of all time.
I also like the (2)
Germany 2014 team with Klose, Boateng, Reus, Hummels, Khedira, Lahm, Draxler, Muller, Podolski, Schurrle, Mertesacker, Schweinsteiger, Neuer, Kroos, and Gotze.
That's the team that defeated Brazil 7 to 1 in their own home, and in their own World Cup, and made this funny celebration after defeating Argentina:

The Galactics that had Casillas as the goalkeeper, Helguera, Salgado, and Sergio Ramos on the defense, Roberto Carlos was the lateral flyer, and the rest of the team was Raul, Michael Owen, David Beckham, Luis Figo, Zinedine Zidane, and Ronaldo.
You can't go wrong with that:

For England I like Manchester United, Liverpool, Arsenal, and Chelsea. I guess Manchester City is not bad since they have De Bruyne.
For Spain I do like Real Madrid, and I do dislike Barcelona, but I admire many Barcelona players, and I also like Valencia, Atletico Madrid, and Cadiz.
For Italy I like the Inter Milan, AC Milan, Juventus, Roma, Lazio, Fiorentina, and Parma.
For France I like Paris Saint-Germain, Monaco, Lyon, Marseille, and maybe Nantes too.
For Germany I like Borussia Dortmund, Bayern Munich, Bayer Leverkusen, Schalke 04, Stuttgart, and maybe Welder Bremen.
For Portugal I like Benfica, Sporting, and Porto.
For Netherlands I like Ajax, and PSV.
From the rest of the world I like Galatasaray, Olympiacos, Boca Juniors, Santos, River Plate, Panathinaikos, Shakhtar Donetsk, Dynamo Kiev, and Celtic.
By the way, Argentina national team from recent years isn't bad as long as both Messi and Di Maria are on the field, but it can always go wrong in many ways.
Uruguay also has had good players just like Netherlands, but they always fall short.
The teams that surprised me the most however were France 1998 that I watched as a kid, and Spain 2010 that also won, but to be fair they all had very good players.
I respect Italy 2006 with Cannavaro, but I'm not a fan of France 2018, I would rather see any Yugoslavian country win at this point.
