Rio Haryanto's manager has clarified reports that the Indonesian rookie might not complete the entire 2016 season.

It was reported this week that, although backed by Indonesia via the state-owned oil company Pertamina, Haryanto's entourage is still looking for more sponsorship to deliver everything promised to the Manor team.

His manager Piers Hunnisett, however, denied the claims, telling GMM: "All is confirmed for a full season."

Haryanto, 23, had a troubled start to his Formula 1 career this week, going off track more than once and lagging teammate Pascal Wehrlein's pace by several seconds.

Asked if the long-time GP2 driver simply pushed the Mercedes-powered car beyond its limits, new racing director Dave Ryan confirmed: "I think so. Frankly, I would have been surprised if there were no incidents. As long as he is learning, it's okay."

The new season gets underway with the Australian Grand Prix on March 20.
