Slovakia was much better then Portugal in the first half and its a shame that they didnt score a goal and after a couple of misses Bruno Fernandes with a beautiful goal punished them and i think Portugal has opened them even more and can score two more goals to finish this match.
Yes, surprisingly Slovakia shows high pressure and the Portuguese play lazily. They are probably very upset that Fernandes, due to his individual skill, tipped the scales in favor of Portugal and now despite the fact that Slovakia played better than Portugal in front. But in fact, this is a common picture when two teams of different classes play - I think that Portugal has the resources to speed up if the need arises, but for now they are playing in energy-saving mode.
