Red Bull's lock-out of the front row promises a thrilling multi-car duel down to Turn 1, but as a priority Horner wants his driver to remain out of trouble and work together to keep their rivals at bay after the launch from the grid.
Daniel Ricciardo has denied Max Verstappen the chance to become the youngest man in Formula One history to claim pole position after beating his Red Bull team-mate with a sensational flying lap in Mexico.
Speaking about his approach to the start of the Grand Prix with the long 900 meter run down to turn one, Hamilton admitted that he has one eye on the championship rather than the Grand Prix saying, "We saw what happened past year with the red vehicle behind, so I don't know".
The other factor is that Vettel must win all three remaining Grand Prix if has a hope of taking title honors for his own and the Ferrari man's task looks hard as he starts directly behind Hamilton in fourth. "Considering how bad yesterday was for us, and so I really want to say a big thank you to everyone who's back at the factory who've been working hard overnight and also the guys here, to rectify the issues we've had and get the auto back into a sweeter spot".

Verstappen lost out by 0.026, with Ricciardo setting a track record time of one minute 14.759 seconds, and he did not try and hide his disappointment.
"The whole qualifying was crap", the deflated Dutchman said. "We tried to make the best of it, I thought we had enough but it's still good to be second".
The pole was only the third of Ricciardo's career and both of those previous ones came in the tight and twisty confines of Monaco.
Immediately after qualifying, Hamilton was asked if he would take a cautious approach to Turn 1, and replied: "Well you saw what happened previous year with the red vehicle behind, so I don't know".
"You could hear how happy he was on the slow-down lap, so really pleased for him", Horner said. "We will get a good tow from the two in front so hopefully I can gain a position".
Hamilton, who only needs to finish seventh to secure the championship, was satisfied with third.
