With a "really good chassis" and two "high-skilled" drivers, Franz Tost says it is only reliability that is preventing Toro Rosso from grabbing P5.
Ten races into this season, Toro Rosso are seventh in the Constructors' Championship on 31 points. That's just eight short of fifth placed Force India.
However, it is not their rookie line-up that has cost Toro Rosso, rather it has been engine or car troubles.
"To score points you must see the chequered flag and our main problem is reliability," said Tost. "We have a really good chassis, we have two high-skilled, young but mature drivers.
"Unfortunately our reliability isn't as good as it should be, because from twenty possibilities to see the end of the race we managed only to do it eleven times.
"That means nine non-finishes and with this high figure you cannot expect to finish in a position which is our goal – fifth position in the Constructors' Championship."
The team boss, though, believes that if Toro Rosso can up their reliability, his pre-season target of fifth in the Championship is doable.
"At the beginning of the year I thought we might be in a position to challenge for a top five position in the Constructors' championship, having seen the figures from the wind tunnel and also the results of testing.
"And now I still tend to think we can do it, especially after our strong result in Budapest, as there are now only 8 points separating us from the team that is P5."
