Chelsea have launched a surprise bid for Crystal Palace midfielder Michael Olise.
The France U21 international is the subject of a 39m offer from the Blues - 4m above his buyout clause.
Manchester City are also interested in Olise this summer.
Transfer expert Fabrizio Romano is reporting: "Chelsea and Manchester City have both Michael Olise in their list. Understand there's release clause into his contract around 35m.
"Both clubs are waiting for clarity about his conditions as he picked up injury last month."
Olise is recovering from a knee strain collected at the U21 Euros in June.
