Croatia's performance in the group stage is brilliant, their midfield duo Luka Modric and Ivan Rakitic possess with strong attacking power as well as eyeable show. Adding in-form Ivan Perisic, Croatia's midfield collocation could match with Spain's deluxe midfield line. However, Croatia's weakness is also visible. First of all, their key player Luka Modric still suffers from injury, if he could not play or give out his normal strength, Croatia's dominance in the midfield line would largely reduce into an inferior level. What's more, Modric's alternative Mateo Kovacic could not act like a leader, which was showed in their Czech Republic match. In the meanwhile, Portugal are also struggling, Cristiano Ronaldo's back on track could not offset their overall gloomy form. Players' condition is not that bad, but their play style is simple and rusty, this could be found in their group stage encounters with several "soft sides". If they could not fix this problem, Cristiano Ronaldo and Portugal International's adventure in France would see its end.
