Romain Grosjean says his immediate focus is on improving Haas' position in Formula One, rather than dwelling on his next move after 2018.
Team owner Gene Haas recently said he expects to take an unchanged line-up into 2018, meaning Grosjean will partner Kevin Magnussen again next year. The Frenchman had been tipped as a possible candidate to replace Kimi Raikkonen at Ferrari if the team decided to part ways with the Finn.
Though there has been no official confirmation of a contract extension by the Haas team, Grosjean is happy to remain part of the American team's project for another season.
