Tottenham midfielder Ndombele was unhappy under Conte and the players wanted to leave the team in the winter window.
Tottenham Hotspur are currently in talks with Paris Saint-Germain on a loan transfer from Ndombele. Players are related to loan to Greater Paris and then choose to buy.
In this case, Tottenham boss Conte wants to bring in a replacement for Ndombele in the winter window. AC Milan midfielder Casey became Conte's preferred player, as was Roma midfielder Villerotu.

AC Milan midfielder Casey's contract in the San Siro has entered into the final months. Negotiations on renewals between players and clubs have reached a standstill. Milan clubs are reluctant to meet the players' demand for an annual salary of 8 million euros.
In this case, the Rossoneri sold Casey in the winter window to recover some of the losses so that the players would not leave in free. However, Casey is a key player for AC Milan and his departure in the winter window could affect the Rossoneri's results this season.
What trade-offs AC Milan will make remains to be seen.
If Milan ultimately decide not to shoot Casey, Spurs will also target Roma midfielder Villertula.
Roma's winter window loan from Porto to Oliveira has the potential to affect Villeto's playing time and could prompt Villette to leave Roma.
However, whether Spurs can buy Casey or Villeroy ultimately depends on whether Ndombele can leave Spurs.
Although foreign media reported that Ndombele was related to the transfer to Paris Saint-Germain. However, whether this can be achieved is still unknown.
Remember last season, Spurs player Alli also had to do with the signing of Paris Saint-Germain on loan in the winter window, but in the end it was not resolved and no deal was realized.
