Tanguy Ndombele has so far refused to confront Spurs boss Nuno Espirito Santo after he was left out of the squad to face Arsenal, according to reports.
Nuno confirmed on Monday that midfielder Ndombele, who has not been involved in pre-season, is not injured.
Asked why the Frenchman had not featured, Nuno said: “Because you can see he is not in the right moment to join the group in terms of competition.
“No, he is not injured. (It is) not about that, it is about deciding who we want to take.”
After struggling in his first campaign with Tottenham, Ndombele had a better season last term, chipping in with three goals and two assists in 33 Premier League appearances.
Spurs fans will still be demanding to see big improvements from the midfielder this season after the club spent £55m on the former Lyon man.
Ndombele was available to play against Arsenal in Sunday’s pre-season friendly but Nuno decided not to include the France international in the squad.
The Athletic claim the 24-year-old is ‘weighing up his options’ with a transfer away from Tottenham this summer understood to be a ‘possibility’.
The ‘expected departures of his close friends Moussa Sissoko and Serge Aurier will be a big setback’ after not playing a minute in any of Tottenham’s friendlies.
Ndombele ‘does not like confrontation and has not spoken to Nuno about his omission from the team’ and it ‘would be a big surprise’ if he featured against Manchester City in Spurs’ first Premier League match of the season on Sunday.
Some at Spurs ‘fear that selling him could become a source of regret given what he is capable of’ with the midfielder showing glimpses of his talent last season.
Meanwhile, former Premier League striker Noel Whelan thinks the north London club should sell Ndombele and bring in a replacement “swiftly”.
Whelan told Football Insider: “They’ve had problems with Ndombele before. He has not been an easy player to deal with since he came into the club. Jose Mourinho found that out.
“I think Hojbjerg is a similar kind of player to Ndombele. Do you need both of them? Probably not. There is enough midfield players at Spurs. Ndombele has got better and better but I do not think he is indispensable.
“When players are not happy and do not fit into a culture or dressing room of players, the best thing to do is get them out and get as much money as possible for them.
“Get him out and bring in someone else swiftly, a player who is a better fit for the changing room. You cannot have disgruntled players because it will spread.”
