Carlos Sainz says he has "a lot of trust" that Red Bull will do the right thing for his future when he starts negotiating about 2018 and beyond later this year.
Sainz was promoted into Formula One by Red Bull in 2015 and placed in junior team Toro Rosso, where he is currently competing for the third season. Last year he was overlooked by Red Bull as it decided to promote Max Verstappen to the senior outfit, swapping the teenager with Daniil Kvyat.
Despite being linked to Ferrari and Renault in 2016 Sainz was eventually retained by Toro Rosso and he expects this year's discussions will begin before summer break.
