The F1 2018 season could be a humdinger 

#4 Williams

Sirotkin was preferred over Robert Kubica for a spot in the team

Lance Stroll:

Everything he does will be viewed through the prism of the dad's cash reserves, until he wows with talent and performances on Sundays.

It's up to him to show that Baku podium last year was not fortuitous. Expect a tough year for him as Williams was not that quick in the winter testing.

He has had a privileged entry and so harsher yardstick will be used to judge his progress and prowess.

Sergey Sirotkin:

The general rant goes that Williams has sold their soul to the devil with a second 'pay driver' and not picking the sentimental favourite Robert Kubica.

Well, those circumstances make the focus on the Russian rookie a tad bit fiercer, with knives ready to be out at the first crash. Besides, they have a very capable reserve driver in Kubica to take over in case of any eventuality.
