Yes they can, the opponent is very weak even on their optimal form, and this is far from the case.
Let us start with a quote, and eventually we will see if this true:
"The starting XI for Friday's game against Scotland has already been decided with: Neuer, Kimmich, Tah, Rüdiger, Mittelstädt, Kroos, Andrich, Musiala, Gündogan, Wirtz and Havertz. Meanwhile, Füllkrug, Sané and Groß are the three players which Nagelsmann considers to be part of the 'extended starting eleven' and thus have the highest chance of playing time [@BILD]

Now is this a good lineup? There are naturally speculations of the physical presence of Havertz and the form of Gündogan. Shoud Germany have Sane upfront? Soon we will know, but at there has been enough time in the German camp to prepare for this tournament on their home ground.
Germany have now failed 3 championships in the but at home they are definitely one of the superpowers and favorites to win among other several top challengers and usual suspects France, England, Spain, Portugal.. the list of classy sides is very long and this will be an exciting tournament!
Last year Scotland did beat both Spain and Norway in their qualification path, but the form has been horrible recently. They have won only two of their last 10 games, and the opponents were Cyprus and Gibraltar! The Netherlands destroyed them by 4-0, they lost to the poor Northern Ireland side, and the latest game v Finland was another disaster. A draw vs a very weak Finnish B team. The defense is led by a player from the bench of a Champioship team, Norwich's Grant Hanley.
The Scottish player material has little width, they lost Lyndon Dykes, Nathan Patterson, and Aaron Hickey before the tournament, Andy Robertson and Lawrence Shankland have minor doubts, and there are doubts even about McTominay.
It is indeed Robertson in the left and John McGinn - Scott McTominay pairing in the middle of the pitch who can create something for the Scots.
Germany have not played competitive matches for some time, but the performances and results in the friendlies are promising:

Scotland are among the weakest sides in this tournament, they miss class and form, and Germany are ready. Would you like to face a German side that is ready? Thought so. easy and comfortable home win for the opening game.

是的,他们可以,对手即使在最佳状态下也是非常弱的,但事实远非如此。
让我们从这句话开始,最终我们会看到这句话是否正确:
“周五对阵苏格兰的首发11人名单已经确定:诺伊尔、金米奇、塔赫、罗德·<s:1>迪格尔、Mittelstädt、克罗斯、安德里希、穆西亚拉、格<s:1>恩多安、维尔茨和哈弗茨。与此同时,内格尔斯曼认为,法尔<s:1>克鲁格、桑纳尔和格劳斯是“延长首发11人名单”中的三名球员,因此他们获得出场时间的机会最大。
这是一个好的阵容吗?人们自然会猜测哈弗茨的实际存在和格<s:1>恩多安的形式。德国队应该让萨内上场吗?很快我们就会知道结果了,但是德国人有足够的时间在他们的主场为这次比赛做准备。
德国在世界杯上已经三次失败,但在国内,他们绝对是超级大国之一,是其他几个顶级挑战者和通常的怀疑对手法国、英格兰、西班牙、葡萄牙的夺冠热门。优秀球队的名单非常长,这将是一场激动人心的比赛!
去年,苏格兰在出线之路上击败了西班牙和挪威,但最近的状态却很糟糕。他们在过去的10场比赛中只赢了两场,对手是塞浦路斯和直布罗陀!荷兰队以4:0击败了他们,他们输给了贫穷的北爱尔兰球队,而最近与芬兰的比赛又是一场灾难。平局对阵非常弱的芬兰B队。防守由一名来自英冠球队的替补球员,诺维奇队的格兰特·汉利领导。
苏格兰球员的材料宽度很小,他们在比赛前失去了林登·戴克斯、内森·帕特森和亚伦·希基,安迪·罗伯逊和劳伦斯·尚克兰也有一些疑问,甚至麦克托米内也有疑问。
左路的罗伯逊和中路的约翰·麦金-斯科特·麦克托米内的组合确实可以为苏格兰人创造一些东西。
德国队已经有一段时间没有参加正式比赛了,但友谊赛的表现和结果都很有希望。
苏格兰是本届杯赛中最弱的球队之一,他们缺少水平和状态,而德国已经准备好了。你想面对一支准备好的德国队吗?这么想的。轻松和舒适的主场胜利为揭幕战。
