"He really wants to keep him," said Hoeness, after holding talks with Van Gaal. "We will not let Ribery go."

"Most clubs only ended their season (recently) and when the players go on holiday, the bosses start with their planning," he told Munich's Abendzeitung newspaper.
"There will be enquiries for Ribery in the next four to six weeks, I'm sure.
"But we have not had any decisive enquiry and we are not interested in any of the rumours in the English press.
"We will be polite, but we will not negotiate. We are not going to celebrate on the telephone when somebody offers a certain amount."
Van Gaal arrived in Munich on Monday and has also addressed the issue of Luca Toni, who seems to be surplus to requirements following the signing of Mario Gomez from Stuttgart and Ivica Olic from Hamburg.
Unlike with Ribery, Hoeness would not hang up the phone immediately on an offer for the Italian.
"In general, four strikers are enough, but if we have five, then we have five," he said.
"We will not be sending anybody away. But if somebody comes to us and wants one of our strikers, then we will talk."
