Portugal x Poland
Portugal has been the best team, statistically, after Germany. Also, they are a personal favourite of mine. They have a good defence, good players in attack, a strong and versatile midfield, very good depth in many positions.
They lack a true striker, a true No9, but that's their only problem. Poland is not a brilliant team. Their hopes were to defend well, and hope Lewandowski has a good tournament, but so far, this has not happened. Lewa did not score at all. Poland's defence held well, but the attack is very modest. I don't see how Poland's attack could trouble Portugal.
