Jorginho says Chelsea must be more clinical if they want Champions League success.
Speaking ahead of Wednesday's clash with Lille, the Italy international commented only Chelsea only scoring two goals against Brighton last Saturday, despite having 24 attempts.
"It is important because we needed to create a lot [to score against Brighton], but I think we need to be better because we can't create how we did and score just two goals," Jorginho told Standard Sport.
"These [Champions League] games, you can't make a mistake because every team is very good. They [opponents] can create just one chance and can score. So we need to be more strong with our mentality to defend."
He added: "The Champions League is very difficult, but we are ready to go everywhere to try to win."
