Trent Alexander-Arnold's injury leaves Jurgen Klopp to look at a new approach as the campaign continues. Reds would need to overhaul their tactical approach seeing as Trent Alexander-Arnold would not be joining back for a significant period after he limped off the field on November evening. For the defending champions through the in-form Sadio Mane, Mohamed Salah and Jordan Henderson bring good news. But Liverpool's tactical approach relies on Alexander-Arnold and Andy Robertson. The England man has already provided three assists for the season. Without Virgil van Dijk Liverpool's backline would now undergo changes for the season. Young defender Neco Williams and vice-captain James Milner were brought in as a replacement for the player at Etihad but would fail to his shoes. Liverpool is in for a tough ride.
