There's a real confrontational edge to the game in these opening stages and it's making for an intoxicating watch.

Great kick-chase from Hull KR and Joe Burgess leads it as they pin back Matt Dufty behind the try-line.

We talk about the pre-game predictions and who fancies what but the game's played on the pitch.

Based on the 10 minutes we've had, it's an even game and anybody's to take.

Whether or not that's a try, you have to give Warrington credit for taking the game to Hull KR early on here.

I think that's a wise move. If they lay an early marker down, I think they have the ability to preserve a lead today.

The referee's call stands.

Papua New Guinea centre Rodrick Tai is guilty of ripping the ball out of Jack Broadbent's hands in the tackle and so Adam Holroyd diving on the loose ball counts for nothing.

Warrington and Adam Holroyd think they have the game's first try.

Referee Liam Moore says no try on-field, but we are going upstairs.

Nothing in it at all. That was a fair challenge for me.

I think Warrington have got a freebie there.

Two men in the area, coming together, what do you do? Not let him tackle him. You're always going to make with the head in that area. It's nonsense.

Referee Liam Moore takes his time and decides that it is a Warrington penalty and no further punishment for Joe Burgess.

There is so much muscle on show, especially in the Hull KR line-up.

These early minutes are all about setting a marker, but hey, that's a late one from Joe Burgess on opposite number Josh Thewlis as the Warrington wing fields a bomb from Mikey Lewis.

Is it a natural rugby collision or something more sinister?

I'm going back 12 months ago.

I'm looking at a Warrington team that did similar things in the first 10 to 15 minutes last year and it didn't work out for them.

They've still got to respect the ball, you've still got to take a chance but you've got to look after the ball as well.

Warrington try to move it wide on the third tackle, but Josh Thewlis can't take Rodrick Tai's .

Mikey Lewis loved that as the ball goes into touch.

The Man of Steel looks pumped for the big occasion.

Is that a high shot from Jared Waerea-Hargreaves on Paul Vaughan? Kiwi on Aussie.

Vaughan slipped a touch in his apporoach, so nothing more than a penalty as it was high, and decent possession for the Wolves.

Hull KR with the first set and carries from each of their props, Jared Waerea-Hargreaves and Sauaso Sue.

Those two fellas take some stopping but the Wolves defenders do just that.

I think Warrington will benefit from the fact that there's not a massive amount of expectation on them.

Last year, although Wigan were favourites, it was very much 'it's Sam Burgess' first year, are they going to turn into a force">They are trying to treat it like any other game. The problem is any other game for Warrington hasn't actually been that good this season.

Let's hope for an absolute corker of a game from the seemingly unstoppable Robins and unpredictable Wolves.

Both Warrington and Hull KR faced heartache against Wigan Warriors last year. The Wolves in the Challenge Cup final; KR in the Super League final.

But today, one of them is guaranteed a trophy with their name on it - which side will it be?

So, as expected, Warrington captain George Williams returns from an ankle injury and starts for the Wire today.

Despite Hull KR's dominance in Super League this season in comparison to injury-plagued Warrington's form, I'm not sure you can make the case that this is going to be a cakewalk for them.

I'm expecting an energetic, difficult game for both sides. With Williams and Marc Sneyd in their ranks, I think Warrington are going to be a tough nut to crack.

Fine wins in tight games over St Helens and Leigh have brought Warrington back to the final for a second time under Sam Burgess.

Can they go one better than 12 months ago?

Third round: Whitehaven (A, 44-4)

Fourth round: Widnes Vikings (A, 26-16)

Quarter-final: St Helens (H, 20-12)

Semi-final: Leigh Leopards (N, 21-14)

Like with their form in the Super League, Hull KR have been ruthless and efficient in their path to Wembley.

There was a memorable derby success away to local rivals Hull FC and a strong-arm showing against Catalans in the semis as they chase only a second Challenge Cup.

Third round: York Knights (A, 44-2)

Fourth round: Oldham (H, 40-0)

Quarter-final: Hull FC (A, 32-16)

Semi-final: Catalans Dragons (N, 36-12)
