Red Bull boss Christian Horner has said that the energy drink firm is looking at younger drivers.
"We are looking at the 13 and 14 year olds," he said, "because otherwise there's not much there."
On the subject of Daniil Kvyat, who was recently confirmed as a Toro Rosso driver for 2017, despite being dropped by Red Bull racing earlier in the year, Horner said: "We believe in him."
"On the outside, he looks like a tough Russian but he's a sensitive guy, which his return to Toro Rosso showed," he is quoted by Auto Motor und Sport. "But the last races have shown that he is well on the way back to being the old Kvyat."
