Gilberto's proposed move to Tottenham from Hertha Berlin has collapsed, according to the Bundesliga club.
The player underwent a medical in London earlier this week after both clubs had reached an agreement over a fee.
Spurs boss Juande Ramos was keen to sign Gilberto as he is short of options at left-back, with Gareth Bale and Benoit Assou-Ekotto both out with long-term injuries.
However the deal has been called off after results of a second medical on Wednesday 'prevented a contract between the player and Tottenham Hotspur from being concluded to the original conditions'.
"The Brazilian national team player Gilberto will fulfil his contract until June 2008 with Hertha Berlin," announced the Bundesliga side on their official website.
The German also hit out at Tottenham for the move falling through saying: "Hertha BSC and Tottenham Hotspur reached an agreement over the transfer of the player after the statutory medical last Sunday, when all conditions for a transfer were fulfilled," added a Berlin statement.
"Which is why it is all the more incomprehensible for Hertha the way Tottenham have now acted."
The news is a blow to Ramos as he had looked to add Gilberto to his signings of Alan Hutton, Chris Gunter and Jonathan Woodgate.
