Bayern Munich CEO Jan-Christian Dreesen said Tuesday it would be “foolish” to let Luis Diaz leave while confirming Michael Olise would stay with the Bundesliga champions next season.

Speaking at a press club event in Munich, the Bayern boss shot down speculation the club’s star wingers could be headed out the door.

Olise, who impressed in France’s run to the World Cup semi-finals, has been linked with Real Madrid for weeks while some have speculated Diaz may be set for a big-money move to Saudi Arabia.

“It’s surprising to see what gets said when you know the truth yourself; it’s interesting,” the 58-year-old said.

Dreesen said Olise would “obviously” be at Bayern next season and said he had received “zero” calls from Real “and not a single letter, fax or email either.”
