It was yet another bad performance from Croatia, toothless in attack and in panic mode whenever there's a cross coming into our box. I'm really not confident we'll even pass the group playing like this.
And it is more than obvious that some old players cannot be replaced so easily - and above all I mean Mandzukic who was definitely a class above the strikers we have now. You can't beat anyone if you don't score goals, which is the biggest lack that Croatia currently has - with of course a defense that is not coordinated and often seems panicky.
I don't think it's so unattainable to pass the group, because it would be enough to achieve one victory and two draws for that goal - and regardless of England being the big favorite, they didn't show impressive football in the preliminaries either - a 1-0 victory against Austria and Romania - while Scotland scarcely defeated mighty Luxembourg with great difficulty (0-1).
Far from looking as good as in Russia, but it is no longer the same team, and we should all be aware of that.
I would not count out the veterans playing in this tournament so soon,,, I do agree when you see teams like England full of young players, and a slower team like Croatia, you fear for them. But do not forget in these short and KO rounds,,, energy is not all you need but experience. The problem though is as cryptofrka mentions the panic when cross comes in. That is supposed to be something pros do not fear at all and reminds me of my supposedly experienced team I support;)
You are right of course but when you give a guess you look at the squads in that very moment for the most part. Sure history and experience has proven to play a role, but when Greece can do it, England also has a chance I guess!
