Chelsea conceded late in the game against Burnley from a set-piece, and thus squandered their three points.
Liam Rosenior has vowed to address the set-piece issues in his defence.
He said: “Set plays are massive in the Premier League, they’re so important.
“Our record this season, defending set plays, is not to the level which is required for us to achieve what we want to achieve and that’s something I need to address.”
