#2 Dennis Praet was poor for Leicester

Dennis Praet was arguably one of the worst players on the field last night - if not the worst. He was part of a three-man centre midfield that totally failed in their bid to control the proceedings, and he seemed trumped, without passion, and unable to pick out a good pass.
None of his long balls or crosses met their intended target, he failed to give a single key pass during the game, and his pass accuracy was just 78%.
Defensively, he offered no aid to his team whatsoever as he failed to get in a tackle or clear the ball at any point. Also, he managed to make only one interception throughout the game.
#1 Trent Alexander-Arnold was exceptional for Liverpool

The 21-year-old has shown his class time and time again so far this season, and he currently looks like the best right-back in the Premier League at the moment. While his defensive output was average at best, he was the best attacking player for Liverpool last night.
When he took the first shot of the game early on, Alexander-Arnold was only showing signs of things to come. Totally commandeering the right wing, he marauded into Leicester's final third to lay up two assists for Firmino to score. During a quick counter attack, he was on point to put a shot past the goalkeeper and increase Liverpool's tally to four.
Interestingly, the young star had 105 touches on the ball, more than any other player on the pitch today. It seems rather unrealistic to run a game from the right wing, but Alexander-Arnold showed everyone exactly how to do it.
