Spain beat Turkey too easily, but Turkey can play well against average teams, and it is difficult for them to play against favorites. Although I do not remember the last time they lost with such a crushing score in official games. They need to pay attention to defense, because conceding so many is unacceptable even against such a strong opponent. As for Spain, they showed that they are in excellent shape, and if the opponent allows them, they are ready to score as much as they want.
Let's say that Turkey is not a fearsome team and it is not even a big one so in Spain he found a team where he could do what he wanted and the formation was clearly superior to that of Turkey and the players had free rein to play excellent football. this is the future and it is today
