Austrian GP: Will Lewis Hamilton and Seb Vettel come to blows again and six more burning issues answered by Sky Sports F1’s Natalie Pinkham

LEWIS HAMILTON and Sebastian Vettel will come face-to-face for the first time since their Azerbaijan dust-up at this weekend's Austrian grand prix.

The warring duo have remained frosty since the German drove into the current world champion in Baku.

And Hamilton recently stoked the flames by 'liking' an Instagram post which accused the FIA of bias in letting Vettel off the hook for his barge.

There is plenty more going on in the fastest sport in the world. Here, Sky Sports' guides you through the weekend's seven big talking points.

1. How hard will it have been for Vettel to apologise and for Lewis to have accepted it?

Pretty tough on both counts. Vettel has a reputation for being feisty and stubborn (neither of which are bad traits for a racer).

He won't have liked being told to apologise, so will have only said sorry when he reached the conclusion that it was the right thing to do himself.

Lewis seems pretty laid back about the situation now. He didn't like being accused of brake testing (the data supported his denial of that) so was glad when that was cleared up.

He still feels strongly that dangerous driving should be dealt with firmly - setting a good example and being good role models are important to Lewis.

2. Will the dynamic have changed between Lewis and Seb?

Mutual respect will prevail. It's clear that they appreciate each other's talent.

They are so closely matched in terms of ability and car performance - so this just ramps things up for the rest of the season. A spicy rivalry is exactly what the sport needs.

3. How will both drivers react on the track? Vettel is facing a disciplinary tightrope and risks a one-race ban if he picks up another three penalty points. Will he drive cautiously all weekend?

Cautious isn't a word known to either driver if you look at their track history. Racing's in their blood and they don’t know how to drive caustiously.

I guess it ramps up the pressure and jeopardy for them and in turn makes the rest of the season very exciting for all of us fans.

4. Why did the stewards get it wrong in Baku, should the FIA now employ professional referees like in football?

The stewards are former drivers so can empathise with the current crop of racers - whilst still being objective.

They recognise what is dangerous driving and what are racing incidents. I'm sure the stewards aren't always unanimous behind closed doors either...

There are a lot of people in the paddock who feel a ten second stop-go was lenient, then to revisit but not change the outcome, was strange.

If Seb's admission of guilt and issue of an apology was only to avoid further punishment then that's disingenuous. At least he did say sorry though - and only he knows if he really meant it!

5. Will the Force India duo also come to blows again? After clashing in Canada and banging into each other in Baku, Sergio Perez and Esteban Ocon are at each other's throats.

Two of the nicest guys when you meet them in the paddock, and when the race begins they’re both fiercely competitive.

The person most drivers want to beat is their team-mate. When you are driving the same car and sharing the same patch of tarmac it's inevitable (although regrettable for the team) that these things happen.

Perez, somewhat surprisingly, has been very public with his criticism of his team mate today and has suggested Ocon has an attitude problem.

It's like he's rattled by him. Perhaps he should have kept the harsh words behind close doors.

Strong management by their team bosses is essential now and it must be a very difficult task.

6. Was Red Bull's return to the top step of the podium a flash in the pan or will they take the fight to Mercedes and Ferrari?

In terms of pace they're still not quite up with Merc and Ferrari yet, but as we saw on Sunday these races are full of drama, so it's about having the tenacity and wherewithal, along with a decent enough car, to capitalise when things go wrong for the others - just like Daniel Ricciardo did.

Austria and Silverstone are two more power circuits, so don't lend themselves to RB. But then again neither was Baku and they won there.

7. Will Jolyon Palmer finish the race? What about Max Verstappen? Can both McLarens make the chequered flag?

Yes! Certainly for Jolyon and Max. They've had well over their fair share of bad luck so I’m thinking the tide has to turn sooner or later.

McLaren is another thing - fundamental problems aren't dictated by good or bad luck. It's time to find a new engine supplier and quick!
