Four things to look out for this weekend in Singapore!

We are now fast approaching the start of the race weekend in Singapore! We take a look at four different things to keep on eye on throughout the next few days!

Sebastian Vettel must win

It's not a must at all costs win for Vettel, but if he doesn't win and Hamilton scores well, he's in trouble. At this track last year, he started to lose out in the championship battle, and the same could happen if Vettel underperforms. The gap could open up to 55 points if Vettel goes pointless. Another fourth place finish in the style of Monza won't make things much better.

How's Kimi Raikkonen feeling?

Raikkonen and Charles Leclerc have been the F1 stars of the week. We're sure the Ice Man doesn't like the media attention but there's nothing he can do. There was a possibility in Monza that he knew Ferrari were ditching him, and could this lead to further unrest between Vettel and The Finn? Is Vettel going to get the 'support' he needs?

Those sneaky little Red Bulls!

They're not in the running for the title, but we know how well they can perform on tracks like this. Ricciardo hasn't touched a podium since his Monaco win and this weekend could be his greatest chance before moving to Renault. They're bound to cause some trouble and likely to get in the way for Mercedes and Ferrari. Red Bull will have a say on who wins the 2018 championship.

Some slight track changes

Parts of the track have been resurfaced. The second DRS detection point has also been moved 100m earlier. Known as one of the bumpiest tracks on the calendar, will this work change anything?
