Bayer Leverkusen director of football Rudi Voller has revealed the club have rejected a bid from Bayern Munich for Chile midfielder Arturo Vidal.
Bayern are believed to have made an offer of around €10 million for Vidal, who has been at Leverkusen for the past four years, but Voller insists the 2010-11 Bundesliga runners-up will not entertain any approaches for him.
"Our principle is that Arturo is too important to us and we want to keep him in any case, whether the offers come from Munich or Napoli, they are not high enough to force us into a rethink," Voller told Kicker.
New Bayern coach Jupp Heynckes is keen to bring Vidal from his former club but it looks like he will have to turn his attention elsewhere, with Voller adding that he expected the midfielder to be offered a new contract soon.
The Bavarians completed the signing of goalkeeper Manuel Neuer on Wednesday, while striker Nils Petersen has joined from Energie Cottbus and Brazil defender Rafinha from Genoa.
Bayern have also expressed an interest in Manchester City defender Jerome Boateng and Japanese midfielder Takash Ushamu from Gamba Osaka.
