Antonio Conte has backed Alvaro Morata to snap out of his form slump.
The Chelsea striker missed three easy chances in the 2-2 drawn with Arsenal on Wednesday night.
But the Italian says his star striker has been unfortunate and has backed him to recapture the form that has helped him towards 10 Premier League goals this season.
"It is not luck in this period, he has to continue to work and continue to improve," said Conte after the Arsenal draw.
"For a striker it is very important to score, it is a pity, he had many chances to score, but I'm very happy with his commitment and effort for the team."
