Former Tottenham midfielder Jamie Redknapp says they must buy this month after last night's Carabao Cup semifinal defeat to Chelsea.

The 1-0 loss at Tottenham Hotspur stadium sees Spurs eliminated 3-0 on aggregate.

"They [Spurs] are sixth in the Premier League, two points behind Arsenal with two games in hand. This is why Tottenham are in a bit of a predicament," Redknapp told Sky Sports after the game.

"Conte signs elite, ready-made players. He brought Rudiger, [N'Golo] Kante, David Luiz. At Inter he brought in [Romelu] Lukaku, all experienced players. If you're going to give Conte free rein, that's what he will want.

"In the wing-back positions, they ended up playing with [Matt] Doherty today, it didn't really work. You've still got good players there. He's not gone there to finish top six, he's gone there to try and challenge for the title. He wants to be competing. He knows what he needs to do. You've got to back him and you've got to back him now.

"Levy's eye isn't as good as a lot of the managers. You've got Conte, give him what he needs. They need to strengthen. Give him what he needs."

Redknapp added that Spurs need players ready to hit the ground running, having previously signed younger players with the potential to grow.

"[Tanguy] Ndombele has not been a success, [Davinson] Sanchez has done okay, the rest have been hit and miss. You can't buy players hoping they're going to be stars in two or three years.

"I'm excited to see what Levy does now, because with this system you've got to get the right players."
