Chelsea manager Maurizio Sarri says Gonzalo Higuain has room for improvement.
The Argentine has scored just three goals since joining from Juventus on loan in January.
Using the example of former Liverpool striker Luis Suarez, Sarri says time is all Higuain needs to adjust to the Premier League.
"I think that he has to improve. Physically, mentally. But I think also that he will be able to be very useful for us in the last part of the season," Sarri said.
"You know very well that it's not easy in the first months to play in the Premier League, it was a problem also for (Luis) Suarez in the first season at Liverpool he only scored four goals.
"But in the second season he scored 24 goals. So it's not easy for a striker to play immediately well in the Premier League. I think he has time for improvement."
