McLaren has sidestepped reports that Kimi Raikkonen might be in the team's sights for 2019.
It is already rumoured that Daniel Ricciardo is being lined up as a potential replacement should 'number one' Fernando Alonso leave at the end of the year.
PA is now reporting that former McLaren driver Raikkonen, who could be replaced at Ferrari by Charles Leclerc, is also in the frame.
A McLaren spokesperson said: "We don't discuss driver matters."
McLaren are currently fifth in the team standings ahead of the Austrian Grand Prix.
