The report further details that Chelsea will not be prepared to offload the Spain worldwide unless they have a direct replacement lined up for January.
It is understood that the striker's agent, Juanma Lopez, has met with Spanish club Sevilla to hold preliminary talks about a return to Spain.
Now they're studying the economics of a potential deal, with Morata's salary alone set to cost Sevilla around one million euros per month.
Benzema should listen to all the offers on the table and make a decision but it appears his preference would be the Premier League.
Do you think this would be a good move for Morata?
However, he concedes any deal will be hard to get over the line.
Eden Hazard has been prefered to him in recent weeks as Sarri introduced a false nine into his formation while Olivier Giroud has also provided competition for Morata over the last 12 months.
"In his best season at Madrid he scored 20 goals, so he will be able to have a very good second part of the season and he will try to reach his best".
Morata missed the Carabao Cup semi-final first leg against Tottenham on Tuesday night, although this was through injury rather than any imminent move.
