4: Haas is nowhere near their rivals' pace
As Romain Grosjean put it, Haas can't seem to crack Mexico.
Ever since the American team entered Formula 1 in 2016, Hermanos Rodriguez has proven to be a bogey track for the outfit. 2016 saw Esteban Gutierrez and Grosjean finish 19th and 20th out of 21 finishers and 2017 produced just a sole point-finish for Kevin Magnussen.
Despite an upturn in form in 2018, both drivers failed to make it into Q2, P16 and 18 for their drivers. Even worse for Grosjean is the fact that he has a three-place grid penalty for the crash he caused in the US GP. It could be a long race for KMag and RoGro on Sunday.
5: Perez needs a miracle in his home race
The sole Mexican driver on the grid will do well to make the top 10 again in his home race.
Sergio Perez has enjoyed another superb season at Force India, the Mexican is the only driver to make the podium who doesn't drive for Ferrari, Mercedes and Red Bull this year. 13th on the grid for Perez, though, doesn't make good reading for the home support, who will be hoping, rather than expecting, for their man to make the top 10.
But with long straights and a decent car underneath him, the Guadalajara native has the opportunity to overtake. Esteban Ocon also failed to make it out of Q3, Mexico City doesn't appear to be Force India's track either.
Pérez and Ocon did not make it into Q3 due to a strategic move and the wish to have a free choice of tyres to start to Grand Prix.
