Chelsea didn't always play well against each top team in EPL. Chelsea was defeated by Liverpool in matchday 22, Chelsea was beaten by Man United in matchday 15, and they also ever got the defeats against Newcastle and Aston Villa. This team only played well against Man City and Arsenal. So, I think we can't claim that Chelsea always played well against big teams of EPL.
It is true that the final EFL is a special match, Chelsea must have a big motivation winning the match. However, I'm not sure Chelsea can win the match if Liverpool plays with their best lineup. Sure, Liverpool should be the favorite to win the match because they have a better quality and mentality of the players.
Chelsea match statistics this season is very uncertain, sometimes they play well and sometimes they lose to average clubs. For the Carabao Cup final, I think Liverpool deserve to be favorites to win the trophy even though Jurgen Klopp can't field his best squad due to injury. Pochettino is actually also facing a storm of injuries, the difference is that Liverpool is more consistent than Chelsea when faced with a situation like the current one. Chelsea motivation to win a trophy is very big, because they don't want to end the season empty handed without any trophy, while Liverpool are currently favorites in the Premier League and Europa League.
Liverpool and Chelsea have officially announced on the club official website that several of their players have suffered injuries, and it is possible that they will miss the Carabao Cup final. Jurgen Klopp faces a bigger challenge because he has a busy match schedule in four different competitions, the Premier League, Europa League, FA Cup and Carabao Cup. Jurgen Klopp will of course try his best to balance the team in every competition, but Chelsea can take advantage of the fatigue factor of Liverpool players who have a busy match schedule.
