Hertha Berlin have confirmed that they have held talks with Tottenham over Brazilian full-back Gilberto.
The 31-year-old is out-of-contract in the summer but Spurs are keen to take the left-back during this January transfer window.
Hertha have now confirmed that they are in talks with Spurs about a possible deal.
"The door for Tottenham is now so wide open that you can talk about it," said Hertha general manager Dieter Hoeness to Sport1.
"The transfer fee must be high enough so we have enough to commit to a substitute for Gilberto.
"The talks continue. It is and remains the decision of Hertha whether Gilberto moves or not."
Spurs original bid was 1 million euros - but they are reported to have upped this to 1.6 million euros.
Hertha are already planning for life without Giberto and are reportedly looking at FK Novi Sad midfielder Gojko Kacar.
