Chelsea signed Gonzalo Higuain on a six-month loan deal in the January transfer window, but the Argentine has found it difficult in his first two games for the Blues.
Higuain has shown glimpses of what he can do as he usually makes the runs behind the defence, but he’s never found out.
Sarri and Higuain formed a formidable partnership in the Italian league, with Higuain scoring 36 league goals – a record in the Serie A.
However, the 31-year-old could barely register a shot on target against Bournemouth, and Sarri has revealed that the Argentine isn’t in good shape and also needs to improve.
“He can improve a great deal,” Sarri told Sky Sport Italia.
“At this moment, he is not in good shape, probably because he has played very little recently between transfer market distractions and back pain.
“He can grow a great deal over the next few weeks.”
Sarri had revealed Higuain told him after the game against Sheffield Wednesday that the football in England is aggressive.
“It’s not easy to adapt to this championship,” Sarri said ahead of Chelsea’s Premier League game against Bournemouth. The Premier League is so difficult.
“At the end of the game [on Sunday], Higuain said it is so aggressive, but here it’s normal!
“It’s not easy but he has the right experience, he’s a great player, and he has to run to adapt in a few matches. He has to do everything in less than one month, otherwise it’s late.”
Sarri’s brand of football has been questioned in recent weeks with Chelsea losing our last two Premier League games, and the pattern of play has made it difficult for Chelsea to create opening for the striker.
“We are struggling, above all mentally. We had assumed that we learned a certain style of football, but the truth is we never did learn it and are paying the consequences,” Sarri told Sky Sport Italia.
“We haven’t even learned the most basic moves yet. We need to work on the basics, the primary foundations of my football, and only then will we try to change a few things.
“It was a good first half, but we conceded after the restart and then stopped being a team. We stopped attacking or defending as a team, we did everything individually.
“I don’t understand why that happened, because we had 45 minutes to go and could comfortably have turned the situation around if we’d kept our focus.
“Every now and then this team reacts in a way I cannot decipher, so that creates some uncertainty.
“Perhaps some of the steps were inevitable, but we need to understand why we have these mental black-outs and what we can do to stop them.”
