Antonio Conte is desperate for Chelsea to realise the importance of keeping clean sheets.
The Blues have only kept out Burnley in their opening five matches of the season which has also included conceding twice to League One outfit Bristol Rovers in the EFL (League) Cup.
Ahead of Friday night's meeting with Liverpool at Stamford Bridge, Conte has urged his playing group to have a little more awareness of working together to keep out the opposition attack.
"This season, we kept a clean sheet only once, only Burnley, and I always repeat to my players: we must feel the danger.
"Always, feel the dangers during the match. The English league is very difficult, very tough, and it's difficult to manage a result at 1-0 or 2-0.
"It's easier to do that in Italy where you can control the situation. In England in the last 20 minutes, anything can happen.
"For this reason, we must feel the dangers for the whole 95 minutes and never relax - never. This league is so tough. One long ball and you can concede a goal."
