Tottenham owner Joe Lewis and chairman Daniel Levy

Darren Bent believes Tottenham could boost their transfer budget by as much as £50million by selling Dele Alli before transfer deadline day.

The former Spurs and England striker, speaking exclusively to Football Insider assistant editor Russell Edge, insists that the Lilywhites should cash in on the 24-year-old after his fall down the pecking order under Jose Mourinho.

The Times report that the Portuguese boss has decided he wants Dele out of the club but that chairman Daniel Levy is concerned his value has plummeted over the last couple of years.

Mourinho has used the attacking midfielder just twice this season and has left him completely out of the other four matchday squads, including in Tuesday’s League Cup win over Chelsea.

Bent believes that now is the time for Tottenham to sell up and is in no doubt a club will spend massive clash to sign him.

Bent told Football Insider: “I think for all concerned I’d let him go now because if Mourinho’s not going to play him and you’ve still got ambitions of bringing players in, you look to players where you can generate the most money.

“If you go and sell Dele Alli, you’re going to generate at least £40-50million because someone will pay that for a Dele Alli.

“That then will allow you to go out and if you want to sign another player, go and do that. I think that the fact they’re hanging on to him, it’s not really doing anyone any favours.

“For me, I would look at the situation and go you know what, it’s probably best we let him go. He is still a top player, I know he’s lost his way a little bit but we’ve seen signs recently that it’s still in there.

“I would maybe cash in, let him go and enjoy his football elsewhere and if Spurs have ambitions of bringing any other players in, this might be the way to generate the most money. He’s not playing anyway.”
