Waiting for Salah and Mane to return from the Africa Cup of Nations to the club is so long that Liverpool's attacking ability will be greatly reduced during this time.
In the absence of the two main players, it was originally a good opportunity for Takumi Minano to take the position. However, when Takumi Minamino wastes a golden opportunity, when the League Cup can only win a draw, his doubts will be even more acute.
Uncle Scum talked about his frustration at this 11-on-10 but could not fully retreat, the "King of North London" chose to defend low after playing one less person, and our army was like a rat pulling a turtle and could not start.
Brentford are our next opponents and their squad wants to replicate the magical 3-3 draw of September, and our army cannot afford to lose. After Manchester City's head-on defeat of Chelsea, it has become even more difficult.
However, Klopp's options will be limited, with Salah and Mane absent and Divok Origi not recovering after missing from injury last month, and urgent measures may be required in extreme cases.
Takumi Minamino is one of the main candidates for the front line in the case of shortage at this stage. In sports warfare he can provide Jota and Firmino with something different. Tireless running is his main theme on the field. For the head coach, however, there is another option that could give a substitution "plan b" when Minano enters the late game.
In Thursday's game we could see three changes made in the last 20 minutes, one of which was Williams replacing Alexander-Arnold.
The Welsh youngster was ostensibly our wing defender, but as Arsenal retreated deeper and deeper, he almost became a winger, providing effective support in the close-up killing opportunities of Minamno. In addition to this, Williams also sent a low flat sweep pass, causing extreme panic in Arsenal's penalty area.
This is not the first time this season that the 20-year-old has been impressed, being given more offensive authority in the national team and if doing the same thing at club level, I believe he is up to it.
Uncle Scum once said that he was a talented player, and the overflow of offensive talent made the Reds manager not at one point quite sure whether right-back was his real "home". Liverpool already knew that the "little bee" would bet on the attack on Arnold's defensive zone, so it was not impossible to put up a winger to suppress the fire to achieve a counter-effect.
