How many times did they actually do this successfully last night? On only 2 or 3 occasions, they barely troubled the Spanish defence.
What game did you watch? Italy barely gave the Spanish defence any trouble all night apart from when they scored and on maybe one other occasion. Had the game ended 3 or 4 - 1 in favor of Spain, no one would have been surprised because they completely outplayed and created a lot more than the Italians.
I think most people came to that conclusion because they haven't been following the Italian team and were surprised by the type of football they played this tournament.
Statistically (chances created, goals scored, possession), Spain was superior before the game kicked off last night and it showed clearly during the game.
I also think the Italian team before last night had faced teams that couldn't fight the possession battle against them, when they did, they were reduced to 30% possession and barely creating anything on the counter.
