Tottenham chairman Daniel Levy

Darren Bent has questioned whether Tottenham properly did their homework on midfielder Tanguy Ndombele after his fitness issues this season.

The former Spurs and England striker, speaking exclusively to Football Insider assistant editor Russell Edge, says that the 23-year-old’s numerous setbacks are a concern for Jose Mourinho and his men.

Having seen the summer signing limp off against Southampton, the Spurs boss admitted it was a “concern” that his midfield maestro was “always injured”.

Bent says that the midfielder’s record of missing games sinch his big-money move is a little worrying and insists he should be playing every single week for the money spent on his capture.

“You’ve got to say it’s a little bit of a concern,” Bent told Football Insider.

“I wouldn’t say he’s injury prone but when you spend that amount of money on a player he really needs to be out there every week or if he’s not out there every week, if it’s tactical fair enough. If it’s fitness-wise, he needs to be out there every week.

“If he keeps pulling up with these injuries then someone’s not done their homework. If this is an issue then someone’s not done their homework.”

Ndombele picked up a hamstring injury just two weeks into the season and has gone on to miss a handful of games since, with 15 top-flight appearances under his belt for the Lilywhites.

He missed out on Boxing Day after telling manager Mourinho that he was not feeling up to playing, the boss insisting it was not because of an injury problem.
