Real Madrid signing Alvaro Morata says Spain's attack face a massive task to overcome the Italian defence.
The Euro 2016 clash between Italy and Spain is on Monday.
“In these past two years, I have learned more than in my entire life before then," the former Juventus hitman told Marca.
“It is much more difficult to score goals in Italy, as they are experts at defending. In Spain you get seven clear-cut chances to finish off, but in Italy you only get a few and have to hit the mark with all of them.
“Italy are always a competitive side and, like in Serie A, it is very difficult to score goals against them. Being there for two years made me a better striker."
