Esteban Ocon's shock Haas exit follows months of mounting tension says Chandhok

Karun Chandhok believes whatever sparked Haas’ decision to abruptly drop Esteban Ocon for the Mexican Grand Prix had been “building up” for some time.

Haas announced ahead of Saturday’s third practice at the Mexico City Grand Prix that Ocon would take no further part in the weekend. Haas reserve and endurance racer Ryo Hirakawa was confirmed as his replacement.
