Kvyat, racing with the team alongside Pierre Gasly this year, has struggled in comparison to his teammate.
Kvyat is currently sitting in sixteenth in the championship standings, where he has only managed to take two points from the six races in 2020 so far, while teammate Gasly is in thirteenth position with fourteen points.
Marko noted how these drivers currently hold eligible super-licences and could drive in F1, but said there is currently no plans to replace Kvyat, while also confirming that Austrian driver Lucas Auer is also not a driver being considered.
“Yes, Daniil does not perform as we expected,” said Marko.
“But we are still just before half-time. Auer is not on my list
“Tsunoda in Formula 2 and Lawson in Formula 3 are currently in positions that qualify for a super-licence. But we are not thinking of exchanging Kvyat.”
Marko also touched on the issues Red Bull's Alexander Albon, who struggled with pace at the recent Spanish Grand Prix, managing a lowly eighth position.
Marko put the blame on his strategy and on race engineer Simon Rennie, claiming the decisions made for the Thai driver during the race made him 'look stupid.'
The Austrian also denied recent reports that the team were looking to replace Albon, saying the team have no reason to replace him as long as he keeps performing.
“The performance in Barcelona, including the strategy, is on the cap of his race engineer," Marko added.
“Alex looked stupid then, not because of his fault. It was his worst race, but as long as he keeps going he is out of the discussion.”
