I see Spain as a huge favorite here.

Japan made a poor performance against Germany and somehow managed to win, thanks to two lucky goals in the second half (one of them from nowhere because action had 0 danger). Although the Blue Samurais have quality in their squad, with many players playing in top european league, they are lacking consistency and experience.

Must remember that in the qualifiers they struggled to score goals (just 12 in 10 games) and beat weak teams such as Saudi Arabia, who ended above them in the group.

Against Germany (a very similar team to Spain, with similar tactics and quality) they were totally outplayed and deserved to lose by 2-3 goals in the first half, just Germany missed many chances and were unlucky. Then against Costa Rica, when they were favorites to win, made another very poor performance, without ideas to break the weak Costa Rica’s defence (who conceded 7 goals by Spain) and the worst: conceding a goal in the last minutes.

According to what I saw in the two previous games, Japan dont deserve to be in ⅛ finals. Changes in the lineup are expected, including Take Kubo whose absence against Costa Rica was notorious.

On the other hand, Spain has been one of the best teams in the tournament so far. Made two great performances, including against Germany (a top team) showing that the team is full of confidence and playing at a very high level. The most important fact: not only 11 players are in good form. Coach Luis Enrique made some changes in the lineup and the team still performed very well, and even players coming from the bench (like Morata) showed a good level.

I’m sure that Spain won’t speculate with the result or possible second position. They are an ambitious team (as seen against Costa Rica) and will go for the win.

Coach Luis Enrique will make changes in the lineup, because the match against Germany was difficult, but as said the whole team is full of confidence and in great form, so changes won’t affect too much to the level of the team.

We’ll see an open game, because Japan most probably will need a victory (one point will be enough for them only if Germany and Costa Rica draw) and it’s an offensive team. This kind of games (with spaces) it’s the most beneficial for Spanish team, who have fast players, good assist mans for the final pass, experienced strikers and fast defenders to stop counters, accustomed to play offensive and stop counters in their teams (Barcelona, Villarreal, Manchester City, Madrid…)

我认为西班牙是最受欢迎的。

日本队在与德国的比赛中表现不佳，但不知何故却取得了胜利，这要归功于下半场的两粒幸运进球(其中一粒进球无处可进，因为动作没有任何危险)。虽然蓝武士的阵容很有实力，有很多球员在欧洲顶级联赛踢球，但他们缺乏稳定性和经验。

必须记住的是，在预选赛中，他们很难取得进球(10场比赛只有12球)，击败了弱旅，比如小组第一的沙特阿拉伯。

对阵德国(一支和西班牙非常相似的球队，有着相似的战术和水平)，他们完全被击败了，上半场输了2-3球是应该的，只是德国错过了很多机会，运气不好。然后在对阵哥斯达黎加的比赛中，当他们被看好夺冠的时候，他们又表现得非常糟糕，没有办法打破哥斯达黎加脆弱的防线(他们被西班牙丢了7球)，最糟糕的是:在最后几分钟丢了一个球。

根据我在前两场比赛中看到的，日本队不应该进入⅛场决赛。阵容的变化是意料之中的，包括久保，他在对阵哥斯达黎加的比赛中缺席是臭名昭著的。

另一方面，西班牙队是迄今为止欧洲杯上表现最好的球队之一。有两场精彩的表现，包括对阵德国(一支顶级球队)，这表明球队充满信心，踢出了很高的水平。最重要的事实是:不仅11名球员状态良好。主教练路易斯·恩里克在阵容上做了一些改变，球队仍然表现得很好，甚至替补球员(比如莫拉塔)也显示出了不错的水平。

我相信西班牙不会对结果或第二名的可能性进行猜测。他们是一支雄心勃勃的球队(就像对阵哥斯达黎加时那样)，他们会争取胜利。

主教练路易斯·恩里克将会调整阵容，因为对阵德国的比赛很艰难，但正如他所说的，整个球队都充满信心，状态良好，所以这些变化不会对球队的水平产生太大影响。

我们将看到一场公开的比赛，因为日本队很可能需要一场胜利(只有在德国和哥斯达黎加打平的情况下，一分对他们来说就足够了)，而且日本队是一支进攻型球队。这种(有空间的)比赛对西班牙队来说是最有利的，西班牙队有快速的球员，有出色的最后传球助攻人，有经验丰富的前锋和快速防守人来阻止反击，在他们的球队中习惯了进攻和阻止反击(巴塞罗那，比利亚雷亚尔，曼城，马德里…)
