Transfer: Olise undergoes Bayern medicals, as Arsenal striker leaves in £4m deal

Michael Olise, of Crystal Palace, is expected to have a medical with Bayern Munich.

Both teams have previously agreed on a deal for Olise, who is preparing to represent France at the Olympics in Paris.

Transfer specialist Fabrizio Romano tweeted on Thursday morning: "Bayern has scheduled the first stage of Michael Olise's medical testing for Sunday.

"Understand that nothing was agreed until today, when Bayern were notified that Palace would receive a portion of any future sales for Olise after triggering the clause.

"This was the key point to clarify."

Sturm Graz has also agreed on a deal with Arsenal to sign attacker Mika Biereth.

Biereth spent the second half of the season on loan with the Austrian club, where he scored nine goals in 22 games.

The two clubs have now agreed on a fee believed to be in the region of £4 million.

Biereth's signing will set a club record for Austrian champions Sturm Graz.
