The Argentina international moved to Chelsea FC on a season-long loan from Juventus in the January transfer window to bolster Sarri’s attack in the second half of the campaign.
Higuain displayed some encouraging signs when the South American striker scored two goals in a 5-0 victory over Huddersfield Town in his third game for the west London side.
However, the 31-year-old’s goals have dried up in a Chelsea FC shirt – and he has only since found the net in a 2-1 win at Fulham at Craven Cottage.
His long-term future at Stamford Bridge remains in doubt with his loan deal set to expire in the summer, although Chelsea FC could retain his services.
Liverpool FC legend Suarez netted four goals in his first 13 games in the Premier League following his move from Ajax in the 2011 January transfer window.
However, the Uruguay international went on to establish himself as one of Liverpool FC’s greatest-ever players with a return of 82 goals in 133 games.
Sarri is hopeful that Higuain will emulate Suarez and start to show signs of improvement despite a slow start to his Chelsea FC career.
“He has to improve physically and mentally and also that he will be useful for us in the last part of the season,” Sarri is quoted as saying by Metro.
“It’s not easy in the first months to play in the Premier League, it was a problem for [Luis] Suarez in the first season at Liverpool, in the second season he scored 24 goals.
“It’s not easy for a striker to play immediately well.
“I think he needs time to improve his condition and be suitable for the Premier League but I think he is able to do it.
“We are lucky because we have Giroud and he is in a very good mental and physical condition.”
We play every three days so we need both.”
