If Sarri is unable to convince Chelsea over Higuain, the Italian will turn his attention to Wilson, who has scored 10 goals in 23 matches in all competitions for Bournemouth this season.
England worldwide Wilson has found the back of the net nine times in the Premier League this season and has registered five assists.
"He has to make a decision and take on his share of the responsibility", said Leo.More news: United States and China to hold trade talks in Beijing next week
Chelsea head coach Maurizio Sarri's first-choice preference to add firepower to his squad is thought to be Juventus striker Gonzalo Higuain, who is now on loan at AC Milan.
"He had a tough moment, he has to put it behind him and get to work".
Sarri has shuffled his pack around due to the injuries to Giroud and Morata by playing Eden Hazard as the striker in recent games.
Higuain joined the Rossoneri with a view to a permanent £32million switch at the end of the season, but Chelsea would be reluctant to spend so much on a player who is already in his thirties.
The 26-yer-old Spaniard has struggled for form since his £65m arrival at Stamford Bridge from Real Madrid in 2017.
