Frank Lampard's Chelsea may be one of the best at restricting opposition shots, but they are the worst in the Premier League when it comes to making glaring errors that lead to goals.
Under-fire keeper, Kepa Arrizabalaga, is the principal offender, but he is not the only one to blame in the Blues line-up.
Since the beginning of last season, players from all departments in the team have chipped in with mistakes that ultimately gifted their opponents a goal.
Lampard has come in for criticism over his side's defensive record after shipping nine goals in the Premier League this season and 63 in 43 games since he took over at Stamford Bridge.
