#3 Perez redeems himself with a podium
One of the most disastrous stories of the 2018 Singapore Grand Prix, was the coming together of the two Force India's that saw Sergio Perez put Esteban Ocon out of the race. The Mexican's race didn't get any better from there, clashing with Sirotkin and essentially ruining his attempted comeback drive. The Mexican received a penalty and the damage on his car put him well back in the race.
Despite the chaos in Singapore, Perez is still an extremely talented driver who is arguably Force India's best and undoubtedly the most talented Mexican to ever grace Formula One. One of the examples of this was his podium in Russia in 2015. Perez came third behind Hamilton and Vettel to take the last spot on the podium, and so far in 2018, he is the only driver to do so that isn't in a Mercedes, Ferrari or a Red Bull.
We see the Mexican coming to Russia with a mission to prove himself and taking advantage of some chaos (that hopefully won't be near him) to push his Pink wagon to third place in the race.
