The France midfielder played the full 90 minutes in Southampton's 2-1 defeat at Anfield on Sunday but Spurs will not be deterred and remain hopeful of securing a deal
Tottenham will make another attempt to prise Morgan Schneiderlin from Southampton as their pursuit of the midfielder goes down to the wire.
Goal understands that Mauricio Pochettino remains determined to land his former player and has sanctioned a bid of around £17 million.
Spurs are confident that Schneiderlin is still determined to make the move to White Hart Lane, despite playing the full 90 minutes against Liverpool on Sunday after it had initially been suggested that he would pull out of training and matches.

Speaking after the 2-1 defeat at Anfield, where Schneiderlin was denied a late equaliser only by an outstanding Simon Mignolet save, Koeman explained that he had no concerns about the France international's commitment.
"He’s a player of Southampton," the Dutchman told reporters. "He wants to play for us – he changed his mind and his mentality last week. He was tired in the last 10 minutes but he is a good player and he is important for us."
Following a summer of big-name departures from the south coast that has brought over £90m in transfer fees to the club, Southampton do not need to cash in on Schneiderlin and are reluctant to let another of their major assets go.
The player has claimed that he has a gentleman's agreement with the club to allow him to leave and Southampton's resolve could be tested by Spurs' final attempt to sign him.
Tottenham lead the race to capture Schneiderlin after the 24-year-old rejected an offer from Arsenal.
Arsene Wenger refused to offer any guarantees of a starting role at the Emirates Stadium, something that is believed to be more likely in Pochettino's side.
Spurs could allow Sandro to leave White Hart Lane if they are successful in their pursuit of Schneiderlin, with Napoli among the Brazilian midfielder's admirers. Sandro was not in the squad who beat West Ham 1-0 on Saturday.
