The head of recruitment at the club of a rumoured Rangers target has admitted they cannot match the offers made to him by other clubs.
It is currently unclear, however, whether the Ibrox side have indeed been in contact with Bauer, who is said to be interesting several English Championship sides as well as Rangers .
But Charlton are hoping the German's heart will rule his head as he approaches the end of his contract at The Valley.
"That [the Addicks' win in last month's League One play-off final] will help in terms of trying to keep him – picking up the trophy and he really, really likes Lee [Bowyer] and Jacko [Johnnie Jackson] as well," Steve Gallen is quoted as having told the South London Press.
"His agent is probably leaning on him. Pat will be thinking with his heart and his agents will be purely thinking with their heads.
"They’ll be saying to him: ‘Charlton have made us an offer and these clubs have made these offers – which are way more. We recommend this’.
"It will come down to Pat’s decision. We would like to negotiate with Pat, but I think it is going to be a tough one – because he will be offered a lot more money to go elsewhere than he is going to get with us.
"His heart will be pulling one way, I imagine, but his head and his representatives will be pulling the other way."
Rangers are expected to strengthen in Bauer's position this summer, having seen Joe Worrall and Gareth McAuley depart since the end of last season.
And that has left Connor Goldson, Nikola Katic and Ross McCrorie - who has played much of his Rangers career in central midfield - as Gerrard's only recognised options at centre-back.
Would Bauer be a good addition for Rangers?
