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.
