Sergio Reguilon is the one undroppable in the Tottenham Hotspur defence.
That is the view of former Spurs midfielder Jamie O'Hara who has delivered a rather brutal verdict on the defenders that Jose Mourinho has at his disposal.
Defensive mistakes have cost the Lilywhites dearly in recent weeks and an error from Eric Dier somewhat set the tone for a 2-1 loss at the hands of London rivals West Ham United last weekend.
It's now five Premier League defeats in the last six games for Tottenham and O'Hara is of the opinion that Mourinho needs to drop Dier as well as Davinson Sanchez, but stick with Reguilon in what would be a revamped back four.
"It's getting embarrassing, isn't it," he told the talkSPORT Breakfast. "We should be turning West Ham over!
"I don’t think we’re going to win anything this season, I think we’ll end up trophyless again, I really do.
"I look at the team and the back-four is just an absolute shambles. I don’t know why Jose keeps playing [Davinson] Sanchez and [Eric] Dier because it’s probably one of the worst partnerships in the Premier League!
"[Japhet] Tanganga plays right-back, but he takes him off and puts [Matt] Doherty there, he’s played [Moussa] Sissoko at right-back, [Serge] Aurier, he just doesn’t know the team.
"The only player you’d say deserves to play in that back-four is [Sergio] Reguilon, I really like him, he’s decent."
"Dier is an alright player but as a centre-half he just looks lost around the box," O'Hara added. "In my opinion he needs to be dropped. I would play Tanganga and Ben Davies at centre-half, play Reguilon on the left and Doherty at right-back.
"Ben Davies is decent on the ball and has got pace, Tanganaga has got pace as well and I think that’s the biggest thing we lack at the back, pace, because we just get exposed all the time."
Reguilon has only just returned from injury, but is regarded - by O'Hara at least - as the latest Tottenham undroppable that already includes Hugo Lloris, Tanguy Ndombele, Pierre-Emile Højbjerg, Son Heung-min, and Harry Kane.
