Liverpool has proven to be a strong team lately in all competitions, not just only in the Premier League games, but also in the Europa cup, FA Cup and the rest cup competition. And this is their first cup final opportunity this season for Jürgen Klopp to lift before his departure as Liverpool's head coach at the end of the season
Liverpool are leading in Premier League and waiting for bad results from Manchester City and Arsenal to see expansions of their gaps against these competitors. Meanwhile, they will have a Carabao Cup final match against Chelsea with so many injured players. A title is a title and Liverpool will not give up in a final match but they must do care more about their race in Premier League. How to beat Chelsea, take the cup and avoid more injuries that will certainly be harmful for their squad strength and competitiveness in Premier League.
Thus wouldn't want to give a chance because if you check, there is no certainty that they will lift the Premier trophy at the of the season and besides they will only be topping the league with 1 point difference should City win their game, so the Premier League trophy opportunity could slip their hands anytime soon, so they will try to take a hold of this trophy at hands and may really mess Chelsea up in this final game.
They are playing well and it's not time to say that they will lose the first position to Manchester City. It's better to lead the league with one point and two points more than two competitors than stand under those competitors. Liverpool are currently standing at a good position, not bad one.
