Chelsea manager, Mauricio Pochettino has analyzed his team conceding too many goals this season.
The Blues have now leaked four goals for three straight games, following their 4-1 defeat at Newcastle on Saturday.
The result leaves them in 10th position on the league table with just four wins in 13 matches.
Pochettino’s men have already conceded 20 goals in the league this season and the former PSG boss said: “No one is talking after Manchester City after we conceded four, like Manchester City.
“The amount we concede is because we need to be more focused and concentrated. Today we concede so easily the goals. That’s why we are disappointed with that.
“It’s a thing that we always talk about and try to be solid in our defensive line. It’s not only about the defensive line. It’s about our performance as a group, like a team.”
