Tottenham are chasing Botafogo defender Doria.
The Mirror says the centre back made his debut for Brazil at just 18 and is extremely highly-rated in his homeland, but Spurs would have to fork out a heavy fee for the youngster.
A third party are in the process of buying the youngster for 9million and are planning to give him a 'shop window' move to Porto or Benfica where they their investment will be returned many times over in the future when he is sold on in a big-money deal.
Botafogo would retain a percentage of the player's economic rights, so Spurs have been told that they would need to stump up more cash to have any hope of winning the race for the wonderkid.
