Substitute Anthony Elanga scored his first Nottingham Forest goal to secure a hard-fought Premier League victory over Chelsea at Stamford Bridge.

Summer signing Elanga, introduced in first-half added time following an injury to Danilo, struck shortly after the break when he raced on to Taiwo Awoniyi's pass and slotted home.

Nicolas Jackson missed a glorious opportunity to equalise inside the final 10 minutes, firing over from inside the six-yard box after being teed up by Raheem Sterling.

Jackson had earlier been denied by a last-ditch block by Willy Boly, while Chelsea's 40 million Pounds deadline day signing, Cole Palmer was introduced by Mauricio Pochettino, as Chelsea chased a response.

Despite dominating possession, territory and chances, the hosts were punished for failing to take their opportunities by a resolute Forest.

A second victory from four games lifted Steve Cooper's visitors to ninth in the table, while Chelsea fell to 11th in the early standings.
