Schalke general manager Horst Heldt has admitted that Lewis Holtby could still leave in the current transfer window despite knocking back an offer from Tottenham on Friday.
The north London club were believed to have contacted Schalke last week after learning that Brazilian midfielder Sandro will be out of action for the rest of the season after suffering a cruciate knee injury.
The German side originally knocked back the proposal but Heldt has revealed that a deal could soon be agreed in the coming days.
"We are in talks about a move in this transfer period, but there is no agreement," admitted the Schalke boss before suggesting that an agreemtn could still be reached in January.
"Tottenham contacted us, because they want Lewis now. We will decide in the coming days."
Holtby starred in Schalke's 5-4 win over Hannover last week as he scored one and provided two assists. Despite the 22-year-old agreeing to leave, Heldt believes that he will continue to perform for as long as he remains in Germany.
He added: "Lewis is a good character, he will give everything to the last day for the club."
Tottenham have already agreed a deal to sign Holtby in the summer but the Daily Mail believes that they could pick up the midfielder for as little as £1.5million if they agree a deal this month.
With Sandro out of action for the rest of the season it seems Spurs could be keen to push through the deal in January as manager Andre Villas-Boas is keen for the club to continue their impressive form and claim a place in the Champions League.
Tottenham's 1-1 draw with Manchester United at the weekend meant they remained in fourth place, four points above Everton who do have one game in hand.
