Bayern Munich CEO Karl-Heinz Rummenigge says Manchester United target Thomas Muller is one of the few players in the game who has no price tag.
The 25-year-old is a confirmed target for the Red Devils but Rummenigge says the Bundesliga champions would be "crazy" if they decide to sell him.
"There are players who do not have a price tag," he told reporters.
"Bayern would be outright crazy if we let him leave.
"We haven't received a phone call from Manchester United and there is no offer in existence.
"I know that Bastian Schweinsteiger had the extremely deserving nickname of 'the Football God' among fans, maybe now Muller can have that tag."
