Spurs boss Antonio Conte wants to sign a new centre-back this summer, with Rengre emerging as a major target.
Negotiations are underway between Barcelona and Tottenham, with more negotiations scheduled for Thursday.
Barca wants to lower his wages ahead of the new season, so he’s ready to leave Rengre to the loan.
The 27-year-old Camp Nou has dropped his position at Camp Nou and is ready for new challenges elsewhere.
If he arrives, Rengre could be the fifth signature of Tottenham’s current transfer window.
The club has already invited goalkeeper Fraser Forster, midfielder Eve Bisma, and wingback Ivan Perisic this summer, and Everton’s forward Richarlison deal will soon be completed.
Tottenham is still keen to sign a new right-wing back, with Middlesbrough Jed Spence as his primary target.
