Cole Palmer has been encouraged to keep working and laughing by manager Enzo Maresca, who believes the goals will then return.
The 22-year-old, who is Chelsea's top scorer in the Premier League this season, has not found the net in his past seven appearances.
However, despite his latest blank against Southampton on Tuesday night, Chelsea returned to the top four with an emphatic 4-0 win over the Premier League strugglers.
While four Chelsea players did get on the scoresheet, Palmer missed a hatful of big chances throughout the game.
But, despite their star man unable to end his goal drought, Chelsea manager Maresca said his team remain "happy" with Palmer - and that the player should also stay upbeat.
"He has to continue to work, continue to be happy, continue to laugh the way he does," Maresca told BBC Match of the Day.
"It is normal to go through a moment where you struggle to score but it doesn't matter. Just continue and you are going to score many goals."
