Portugal is already qualified, but I see them with high ambitions here.

They could qualify with a perfect balance of 10/10 victories. They have been one of the most impressive teams in the qualifiers, displaying a lot of quality, domination, and danger upfront. For me, they are one of the best teams in Europe at the moment, given their quality and the talented players they have in the squad.

They won only 2:0 against Liechtenstein, but had chances to score at least 2-3 more goals, which would have been a fairer result. The mistake there for coach Roberto Martinez was to put an extremely offensive lineup. Therefore, here we might see more midfielders, such as Vitinha, in order to create more football and chances.

They’ll play at home, and this should be enough motivation for them, regardless of the players on the field. They have scored 34 goals in 9 qualifier games, so I’m expecting a good performance here, and hopefully, at least 3-4 goals scored.

On the other hand, Iceland plays for nothing. They didn't manage to qualify, finishing 4th in the group. They achieved some points in the qualifiers but weren't enough and finished below Portugal, Slovakia, and Luxembourg.

They were totally outplayed by Slovakia (4:2) and weren’t able even to avoid a defeat against Luxembourg (3:1). Playing away, they beat only Liechtenstein and lost the other three games (3:0 Bosnia, 3:1 Iceland, 4:2 Slovakia).

Iceland has a very weak squad, with a terrible defense that makes mistakes in every single match.

The previous game finished only 0:1 for Portugal, but there were different circumstances. Iceland was still motivated, playing at home, and played very defensively from the first minute. Now, without anything at stake, it won’t make any sense to be defensive again. They should try to attack and enjoy, and Portugal will find more spaces and chances to score.

For me, the difference between these two teams at the moment is huge, at least 3 goals. Weak teams like Luxembourg, Bosnia, and Slovakia managed to score more than 3 goals at home against Iceland, and given Portugal’s quality upfront, I see them able to score at least 4 or 5.

葡萄牙已经出线了，但我认为他们在这里野心勃勃。

他们可以以10胜10负的完美平衡晋级。他们是预选赛中最令人印象深刻的球队之一，在前场展示了很多质量，统治和危险。对我来说，他们是目前欧洲最好的球队之一，考虑到他们的实力和球队中有天赋的球员。

他们在与列支敦士登的比赛中仅以2:0取胜，但他们有机会至少再进2-3个球，这将是一个更公平的结果。主教练罗伯托·马丁内斯(Roberto Martinez)的错误在于他安排了一个极具进攻性的阵容。因此，在这里我们可能会看到更多的中场球员，比如维金尼亚，以创造更多的足球和机会。

他们将在主场比赛，这对他们来说应该是足够的动力，不管场上的球员是谁。他们在9场预选赛中进了34个球，所以我期待他们在这里有好的表现，希望至少进3-4个球。

另一方面，冰岛却一无所获。他们没能出线，以小组第四的成绩结束了比赛。他们在预选赛中获得了一些积分，但还不够，最终排在葡萄牙、斯洛伐克和卢森堡之后。

他们完全被斯洛伐克(4:2)击败，甚至无法避免输给卢森堡(3:1)。在客场，他们只击败了列支敦士登，输掉了其他三场比赛(3:0波斯尼亚，3:1冰岛，4:2斯洛伐克)。

冰岛是一支非常弱的球队，他们的防守非常糟糕，每场比赛都会犯错。

上一场比赛葡萄牙仅以0:1结束，但情况有所不同。冰岛仍然很有动力，在主场比赛，从第一分钟起就打得很防守。现在，在没有任何利害关系的情况下，再次防御是没有任何意义的。他们应该尝试进攻并享受，葡萄牙将找到更多的空间和得分机会。

对我来说，这两支球队目前的差距是巨大的，至少有3个进球。像卢森堡、波斯尼亚和斯洛伐克这样的弱队在主场对阵冰岛的比赛中都能进3个以上的球，考虑到葡萄牙的前场实力，我认为他们至少能进4到5个球。
