And indeed it was lucky spree! With matches like: against Croatia when they were barely touching ball and in the end managed to score lucky goal in 118 minute, or they won with Poland only because they managed to score 1 more penalty shutout. Their only 2 good matches were the last one in final against France and semi-final vs Wales (just because Wales had some players benched).
Portugal are good but also they were extremely lucky in this tournament.
They played a very cynical game the entire tournament.
They only took risks when in disadvantage because their attack was not the best and they knew it.
Defense wise they proved to be the strongest.
Italy played this defensive game for years and nobody complained. They were in fact praised for doing so.
