The midfielder is furious that Southampton chairman Ralph Krueger announced on Tuesday that he will not be sold this summer despite advanced talks between the Saints and Spurs over a transfer.
Schneiderlin is ready to submit a transfer request and could even refuse to play for Southampton as he believes that the club have broken repeated promises.
The Saints told the France international they would not stand in his way if a big club wanted to sign him when he penned a four-year contract in February 2013.
They repeated the promise last summer when Schneiderlin opted to stay at the club amid serious interest from Arsenal, while the midfielder was assured that Southampton would listen to offers when he told them of his desire to leave St Mary’s Stadium before this summer’s World Cup.
Schneiderlin has seen several team-mates leave the club this summer and does not understand why the Saints should stand in his way, having been willing to sell so many players.
Southampton informed the player’s agent that he would not be sold in a meeting at St Mary’s on Tuesday afternoon, before Krueger conducted a number of bullish interviews insisting that the Frenchman and fellow Spurs target Jay Rodriguez were not for sale.
Schneiderlin, who cost £1.25 million when he joined from Strasbourg in 2008, expressed his anger over Southampton’s stance on Twitter on Tuesday night.
