People NEVER seem to understand that possession football needs very good tactics and teammates that can transition very quickly. While some may think Messi did little to contribute to the game, there are still very glaring underlying issues to Sampaoli's tactics. Although Argentina may seem like a "stacked team", they are hardly very well accustomed to the fundamentals of tiki taka. The likes of Icardi, Higuain, Benega seemed very slow on the ball, no dynamism whatsoever. They lack good attacking fullbacks as well. Argentina is no Barcelona. The only good teams that play with very strong chemistry and understanding with each other are Spain, Germany, Brazil. A good example would be France, one of the most talented squads but hardly any mutual connection or strong tactics. Call me crazy, but I dont see France getting anywhere near the semis or finals of the World Cup.
Tactics wise, if u dont have the players that seem comfortable with possession, tiki taka. SIMPLY DON'T. If u dont have players like Xavi or Iniesta, U SIMPLY CANT tiki taka ur way out. Messi alone cant do it all. I have seen the exact same thing with Sampaoli's Sevilla; they even struggled and lost to a counter attacking Leiceister. With possession football, even teams like Venezuela could comfortably sit back all game because they have nothing to lose. If Sampaoli didnt make possession a priority and get rid of the high pressing to save energy, it would allow some breathing space for Argentina and would likely bait some Venezuela attackers to go forward. It could then create more space for Argentina to penetrate, ultimately springing a surprise attack on them while they are vulnerable.
This is the problem with teams that adopt an extreme tiki taka mindset and have no flexibility, believing its a one size fits all. Teams like Chile, Arsenal, Sevilla suffer the exact same problem. Real Madrid are good example of a team with very good adaptability and flexibility, who could ultimately play both tiki taka and counter attacking. Look at how the likes of Real Madrid's Isco, Asensio, and Ramos injecting almost an entirely NEW life into the Spain NT. It's about adaptibility. The new generation of Spain isn't about just tiki taka, but equally dangerous at counter attacking as well.
