Chelsea playmaker Eden Hazard described new signing Gonzalo Higuain as "unbelievable" in the box after the Argentina global scored twice in Saturday's 5-0 thrashing of the Premier League's bottom side Huddersfield Town.
Higuain burst into life against Huddersfield after a quiet start to life at Stamford Bridge, netting two goals as the Blues hammered their opponents 5-0 in the Premier League at the weekend.
"Sarri is the coach who has got the best out of me as a player".
But Sarri is also looking at using Kovacic in Jorginho's position after Chelsea decided against signing a like-for-like replacement for Cesc Fabregas, who joined Monaco.
Solskjaer: Anthony Martial Needs To Score More Tap-Ins
Rashford, who is now one of the Premier League's most in-form players, has scored six goals under Solskjaer. Manchester United's next fixture is against Fulham on Saturday in the Premier League .
Sarri, aware that Jorginho is central to his footballing philosophy, continued: "We have movements without the ball and, for Jorginho, it's easier I think". We played one of the best games of our season and scored five great goals.
Both sides will also slug it out in the Carabao Cup final on February 24 in one of the Blues hard run in the month.
But, to the relief of everyone, Kovacic replaced Jorginho for the final 20 minutes although Sarri afterwards revealed his decision had been influenced by the former Napoli midfielder feeling pain in his groin. Higuain's arrival on loan from Juventus in January mirrored the signing of Olivier Giroud last season, an aging striker acquired and applied like a sticking plaster onto a malfunctioning team.
Eden Hazard has admitted that he has been impressed by what he has seen from Gonzalo Higuain so far at Chelsea FC. He has the quality to score, and also receive the ball, be a target man, go deep. He's intelligent. In the box he's unbelievable. His form will play a crucial role in determining whether Sarri's side achieve their aim of securing a strong finish in the top four this season.
