Red Bull team principal Christian Horner has suggested the consequences of crashing out in final practice before qualifying at the Monaco GP could be the moment that most impacts Max Verstappen.The Dutchman has endured a difficult 2018 which has seen him have some kind of incident at every race, whether it be a spin in Australia or contact with other drivers at the last four Grands Prix.In Spain, it was only a gentle tap with Lance Stroll at a Virtual Safety Car restart and it wouldn't impact his eventual result which would be a first podium of the year in third.Monte Carlo has never been a happy hunting ground for the 20-year-old however with multiple crashes in 2015 and 2016 and his latest one, coming at the second part of the Swimming Pool complex, meant he was unable to take part in qualifying.“Max’s car was fired up and then we saw an oil leak in the gearbox which had been hidden and that was it,” Horner explained to Sky Sports.“They did their best to get the gearbox replaced, which would have been a five-place penalty, but I have to say both car crews did everything that they could to make it happen.“Today, unfortunately, it wasn’t to be."

What made the incident even worse was it came on a weekend where Red Bull have been dominant with his teammate Daniel Ricciardo leading every session, including taking just his second career pole.

“This place bites hard if you abuse it. Max is a very fast driver, we know that, and this weekend he has a great car," his boss added.

“Nobody will be more frustrated than him. He should have been competing for the front row today. There is no more brutal lesson than what he has just had.”

Now, it will be upto Verstappen to keep his head in what will be a very testing Grand Prix mentally as he tries to make his way from the back around a street circuit where overtaking is almost impossible.

One of his first incidents, with Romain Grosjean in 2015 was a prime example of the then 18-year-old losing patience and he'll be desperate to avoid a repeat on Sunday.
