That is the view of former England defender Danny Mills.
He believes Tottenham could sell Eric Dier following the club spending a record transfer fee of £55million on Tanguy Ndombele from Lyon.
Dier joined spurs back in 2014 from Sporting Lisbon for £4m.
Since then he has gone on to make 155 appearance for Tottenham in the Premier League while also earning himself a call up to the England squad.
However, last season he has dropped down in the pecking order at the club and Mills feels his time at Tottenham could soon be over.
“It could be curtains for Eric Dier,” Mills told Football Insider.
“You fear for him, you really do.
“He didn’t have a good season last year, and I can see him leaving if Tottenham need to recoup some money.”
Ndombele might not be the finished article yet but impressive performances has seen him break into the French national team.
The 22-year-old is regarded by some as one of the best young midfielders in Europe, with comparisons being made to Michael Essien and N’Golo Kante.
And following Ndombele committing to a six-year deal at Tottenham the midfielder admitted he had made the “dream move” to north London to win trophies.
“For me, it’s been a dream of mine since I was a kid to play in the Premier League,” Ndombele said.
“I can’t wait, I’m excited at being able to play in the Premier League and I’m hoping that we can achieve great things with the team.
“I hope to be able to bring what I know I can do – to do my bit for the team.
“The squad works really well together so I hope to start well, integrate, settle into the group and then continue in the same way.
“To win silverware, that’s also why I am here.”
And with his arrival Pochettino now has several midfielders in his squad and Mills doesn’t see the Argentine placing Ndombele on the bench given the amount of money the club paid for him.
“Tottenham haven’t spent an incredible amount of money on Ndombele to put him on the bench,” Mills said.
“When he’s fit, he plays, simple as that.
“Moussa Sissoko will probably be the first choice to partner him in central midfield, with Harry Winks the other main option. He’s had a lot of injuries so can’t be expected to always be available.”
