Gary Cahill believes Chelsea must shore up its defense to become serious contenders both domestically and in Europe.
The former Aston Villa and Bolton center back insists the Blues have the attacking talent to match any team in the world but admits they are being let down by a leaky backline.
Often paired alongside David Luiz, Cahill commonly finds himself as the last line of defense and says he sometimes feels more exposed than he perhaps should be.
"There are times when things aren't as tight or you feel a bit more exposed than usual," he told The Guardian.
He continued to explain, "The other night, against Shakhtar Donetsk, I was thinking: 'Wow, this is a bit end-to-end.' But, for the neutral, it was great to watch. And with the players we have, would people be happy if we were just winning 1-0 every week? At least this is entertaining."
Chelsea seems to have gone into matches this season with the aim of simply outscoring its opponents. While this may have been a fruitful plan so far in the league, Cahill suspects it is not a game plan on which to base a title challenge.
"The first thing the attacking players in the team think about is hurting the opposition and getting forward," he stated.
"Our style is more attractive than people thought last year but it's all about winning games and being disciplined at times. We could have done better in terms of discipline over the last two or three weeks and some of the goals we conceded could have been prevented.
"As a defense, we have to strive for that clean sheet while also giving the attacking players the license to go and create."
