Max Verstappen departed Spa bewildered by a race weekend which resulted in the Dutch drivers' sixth retirement of the season.
The Red Bull Racing driver slowly ground to a halt on Spa's Kemmel straight after seven laps in Sunday's Belgian GP following a failure of his power unit's internal combustion engine.
"It’s now 50 per cent of the races [ended] in retirement," Verstappen told NBC.
"It’s unbelievable, like I said on the radio, I just can’t believe that those things happen.
"Of course, in the beginning, you say maybe it’s just bad luck or whatever, [but] I’m actually competing against Fernando in terms of retirements. It’s unbelievable, I’m not happy at all.
"I am very disappointed for retiring and [for] the fans who buy an expensive ticket to watch and I retire after eight laps. No words."
Verstappen's botched weekend will only add to frustrations which have been piling up this season. Yet, the young charger isn't thinking of moving to greener - and more reliable - pastures anytime soon.
"I’m not even thinking about that, we just need to solve it within the team. Because for a top team those things can’t happen.
"I’m not too worried about the future, what’s happening next year, I just want to finish races and have good results. We worked very hard all weekend, and then again you just retire.
"The results are not happening, so you don’t care about next year or the year after at this time.
"We need to talk. We will always talk about [it]; at the moment I am not a happy person and I look forward to going home."
