Sometimes Chelsea's attack line can be very deadly in front of the opponent's goal. But sometimes they also become very weak and their accuracy is very poor. And yes, it could be said that they wasted too many opportunities that they had in front of the opponent's goal.
In the EFL Cup Final, maybe Chelsea could surprise Liverpool. Because sometimes weak teams in the Premier League can also surprise strong opponents when playing in other competitions outside the Premier League. So I agree that Liverpool must be more careful in this match because Pochettino's squad can sometimes be a tough opponent when they play with more confidence.
I think you're referring to the Chelsea of olden days and not the present Chelsea of today. For more than three consecutive seasons now, there's absolutely nothing deadly about Chelsea's front. In fact, Chelsea has the weakest attack among the top teams in England. They are the only team that is playing without constant attackers and that's one thing killing them and leading to chances miss in every game week. Chelsea is a trophy club and has every reason to win this game considering that Liverpool is faced with injury challenges right now. Although, the odds are against Chelsea because from the record, Chelsea's last six final played in Wembley ended in defeat but this is the perfect opportunity to break the curse and make a change. I believe with the same fighting spirit displayed against Manchester city, crystal palace and Aston villa together with team work, they will definitely make it happen if pottechino plays players at the right position.
